Thus, if you do something to one side of the equation, you must do the same thing to the other side. Doing the same thing on both sides of the equation (say, adding, subtracting, multiplying or dividing by any number on each side) keeps the equation balanced.<\/p>\n\n\n\n<p>A simple equation is considered a linear equation in one variable. That means it involves a polynomial of degree one and with one variable only. Solving a simple equation means we find out the value of the unknown variable.<\/p>\n\n\n\n<p>An <a href=\"https:\/\/www.splashlearn.com\/math-vocabulary\/number-sense\/equation\">equation<\/a> can be compared with a weighing balance with equal weights on both sides. A weighing balance needs to have equal weights on both sides to be perfectly balanced. The same principle will hold in an equality.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"620\" height=\"665\" src=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/09\/comparing-an-equation-to-a-weighing-balance.png\" alt=\"Comparing an equation to a weighing balance\" class=\"wp-image-34124\" title=\"Comparing an equation to a weighing balance\" srcset=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/09\/comparing-an-equation-to-a-weighing-balance.png 620w, https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2023\/09\/comparing-an-equation-to-a-weighing-balance-280x300.png 280w\" sizes=\"auto, (max-width: 620px) 100vw, 620px\" \/><\/figure>\n\n\n\n<p>A simple math equation comprises <a href=\"https:\/\/www.splashlearn.com\/math-vocabulary\/algebra\/variable\">variables<\/a> and constants.

equation. The equation 3x + 2 must equal to 23 once the value has been determined. The equation will hold true even if the Left Hand Side (LHS) is switched out for the Right Hand Side (RHS). The same number can be added, subtracted, multiplied, and divided into each side of a straightforward equation without changing the result.&nbsp;<\/p>\n\n\n\n<p>There are three methods to solve simple equations. They are:<\/p>\n\n\n\n<p>1. Trial and error method<\/p>\n\n\n\n<p>2. Systematic method<\/p>\n\n\n\n<p>3. Transposition Method<\/p>\n\n\n\n<p><strong>Trial and Error method<\/strong><\/p>\n\n\n\n<p>In a trial and error method, we guess a solution to the equation. We find the values of LHS and RHS of the given equation for different values of the variable. The value of the variable for which&nbsp;<\/p>\n\n\n\n<p>LHS = RHS is the solution of the equation.<\/p>\n\n\n\n<p><strong>Example<\/strong>: x + 6 = 10<\/p>\n\n\n\n<p>LHS = x + 6<\/p>\n\n\n\n<p>RHS = 10<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"wj-table-class\"><thead><tr><th class=\"has-text-align-center\" data-align=\"center\">x<\/th><th class=\"has-text-align-center\" data-align=\"center\">LHS<\/th><th class=\"has-text-align-center\" data-align=\"center\">RHS<\/th><th class=\"has-text-align-center\" data-align=\"center\">Is LHS = RHS ?<\/th><\/tr><\/thead><tbody><tr><td class=\"has-text-align-center\" data-align=\"center\">1<\/td><td class=\"has-text-align-center\" data-align=\"center\">1 + 6<\/td><td class=\"has-text-align-center\" data-align=\"center\">7<\/td><td class=\"has-text-align-center\" data-align=\"center\">No<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">2<\/td><td class=\"has-text-align-center\" data-align=\"center\">2 + 6<\/td><td class=\"has-text-align-center\" data-align=\"center\">8<\/td><td class=\"has-text-align-center\" data-align=\"center\">No<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">3<\/td><td class=\"has-text-align-center\" data-align=\"center\">3 + 6<\/td><td class=\"has-text-align-center\" data-align=\"center\">9<\/td><td class=\"has-text-align-center\" data-align=\"center\">No<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\">4<\/td><td class=\"has-text-align-center\" data-align=\"center\">4 + 6<\/td><td class=\"has-text-align-center\" data-align=\"center\">10<\/td><td class=\"has-text-align-center\" data-align=\"center\">Yes<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Therefore, LHS = RHS for x = 4.<\/p>\n\n\n\n<p><strong>Systematic method\/ Balance Method<\/strong><\/p>\n\n\n\n<p>Keep both sides of the equation balanced by performing the same operations on each side. This maintains the equality between the two sides.&nbsp;&nbsp;<\/p>\n\n\n\n<p>In the systematic method, an equation is compared to a weighing balance. The two sides of an equation are two pans, and the equality sign tells us that two pans are balanced. If equal weights are put in two pans, then two pans will be balanced. If we remove or add equal weights to both the pans, then we can still see the pans are in balance.<\/p>\n\n\n\n<p><strong>Example<\/strong>: x &#8211; 5 = 10&nbsp;<\/p>\n\n\n\n<p>Adding 5 on both sides, we get<\/p>\n\n\n\n<p>x &#8211; 5 + 5 = 10 + 5&nbsp;<\/p>\n\n\n\n<p>Thus, x = 15<\/p>\n\n\n\n<p><strong>Transposition<\/strong><\/p>\n\n\n\n<p><strong>The shifting of a number from one side of an equation to another is called \u201cTransposition.\u201d&nbsp;<\/strong><\/p>\n\n\n\n<p>The transposition method is a technique used to shift numbers from one side of an equation to the other. This involves adding or subtracting the number from both sides while changing its sign. This method uses inverse operations.<\/p>\n\n\n\n<p>For example, if a term has a plus sign on the left-hand side, it becomes a minus sign on the right-hand side and vice versa. Transposition helps in isolating the variable and solving simple equations efficiently.<\/p>\n\n\n\n<p>Let&#8217;s see an example to understand this method better.<\/p>\n\n\n\n<figure

You might be surprised to learn that applications of equations turn up in many places besides math classrooms. Knowing how to solve simple equations is a basic math skill used in nearly every academic discipline. Now, let&#8217;s solve some easy equation examples and practice problems to understand the concept better.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"6-solved-examples-on-applications-of-simple-equations\">Solved Examples on Applications of Simple Equations<\/h2>\n\n\n\n<p><strong>Example 1:&nbsp; Write the equations for the following statements:<\/strong><\/p>\n\n\n\n<p><strong>a. Two added to the product of a number and 13 equals 15.<\/strong><\/p>\n\n\n\n<p><strong>b. Dividing a number by 5 equals 25.<\/strong><\/p>\n\n\n\n<p><strong>c. The sum of 5 and a number is 11.<\/strong><\/p>\n\n\n\n<p><strong>Solution:&nbsp;<\/strong><\/p>\n\n\n\n<p>a. Let the number be x.&nbsp;<\/p>\n\n\n\n<p>The equation is (13 $\\times$ x) + 2 = 15<\/p>\n\n\n\n<p>Thus, 13x + 2 = 15<\/p>\n\n\n\n<p>b. Let the number be a.&nbsp;<\/p>\n\n\n\n<p>The equation is $\\frac{a}{5}$ = 25<\/p>\n\n\n\n<p>c. Let the number be x.<\/p>\n\n\n\n<p>Sum of 5 and a number = 5 + x<\/p>\n\n\n\n<p>So, the equation is 5 + x = 11<\/p>\n\n\n\n<p><strong>Example 2: Solve equation <\/strong><strong>x<\/strong><strong> + 4 = 10 using the systematic method.<\/strong><\/p>\n\n\n\n<p><strong>Solution:&nbsp;<\/strong><\/p>\n\n\n\n<p>In the systematic method we treat LHS and RHS as two pans of a weighing balance.<\/p>\n\n\n\n<p>So, for solving equation x + 4 = 10, we subtract 4 from each side.<\/p>\n\n\n\n<p>x + 4 &#8211; 4 = 10 &#8211; 4<\/p>\n\n\n\n<p>x = 6&nbsp;<\/p>\n\n\n\n<p>Thus, x = 6<\/p>\n\n\n\n<p><strong>Example 3: If 5 is added to twice a number, the result is 29. Find the number.<\/strong><\/p>\n\n\n\n<p><strong>Solution:<\/strong><\/p>\n\n\n\n<p>Let the required number be x.<\/p>\n\n\n\n<p>Converting it into equation, we get<\/p>\n\n\n\n<p>2x + 5 = 29<\/p>\n\n\n\n<p>Solving the equation, we get<\/p>\n\n\n\n<p>2x + 5 = 29<\/p>\n\n\n\n<p>2x = 29 \u2013 5 (Transposing 5 to RHS)<\/p>\n\n\n\n<p>2x = 24<\/p>\n\n\n\n<p>x = 12 (Dividing both sides by 2)<\/p>\n\n\n\n<p>x = 12<\/p>\n\n\n\n<p>Thus, the required number is 12.<\/p>\n\n\n\n<p><strong>Example 4: Total number of the boys and girls in a class is 52. If the number of girls is 10 more than that of boys, find the number of boys?<\/strong><\/p>\n\n\n\n<p><strong>Solution :<\/strong><\/p>\n\n\n\n<p>Let us assume the number of boys to be x.<\/p>\n\n\n\n<p>The number of girls will be x + 10.&nbsp;<\/p>\n\n\n\n<p>The total number of boys and girls = x + (x + 10) = x + x + 10 = 2x + 10&nbsp;<\/p>\n\n\n\n<p>It is given that the total number of boys and girls in the class is 52.<\/p>\n\n\n\n<p>Therefore, 2x + 10 = 52&nbsp;<\/p>\n\n\n\n<p>Solving this equation, we get<\/p>\n\n\n\n<p>2x = 52 \u2013 10 (transposing 10 from LHS to RHS)<\/p>\n\n\n\n<p>2x = 42&nbsp;<\/p>\n\n\n\n<p>2x = $\\frac{42}{2}$ (transposing 2 from LHS to RHS)&nbsp;<\/p>\n\n\n\n<p>Therefore, x = 21<\/p>\n\n\n\n<p>The number of boys in the class is 21.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"7-practice-problems-on-applications-of-simple-equations\">Practice Problems on Applications of Simple Equations<\/h2>\n\n\n\n<div
