However, there are things that vary with time and place like temperature, age, height etc. Since these quantities change they are may be called variables.&nbsp;<\/p>\n\n\n\n<p class=\" eplus-wrapper\">In algebra, a symbol (usually a letter) standing in for an unknown numerical value in an equation or an algebraic expression. In simple words, a variable is a quantity that can be changed and is not fixed. Variables are essential as they form a major algebra component.<\/p>\n\n\n\n<p class=\" eplus-wrapper\">We usually use \u201c<em>x<\/em>\u201d and \u201c<em>y<\/em>\u201d to express an unknown integer. However, it isn&#8217;t necessary, and we can use any letter.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"620\" height=\"308\" src=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2022\/05\/Variable-1.png\" alt=\"Explanation of Variable\" class=\"wp-image-4904\" title=\"Explanation of Variable\" srcset=\"https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2022\/05\/Variable-1.png 620w, https:\/\/www.splashlearn.com\/math-vocabulary\/wp-content\/uploads\/2022\/05\/Variable-1-300x149.png 300w\" sizes=\"auto, (max-width: 620px) 100vw, 620px\" \/><\/figure>\n\n\n\n<p class=\" eplus-wrapper\" id=\"0-example-\"><strong>Example-&nbsp;<br><\/strong>Let us take an example of the algebraic expression 2x + 6.

If x = 1, the value of this algebraic expression will be 2(1) + 6 i.e. 8 and&nbsp;<\/p>\n\n\n\n<p class=\" eplus-wrapper\">if x = 2, the value of the algebraic expression changes to 10. Hence, we can say that the value of the algebraic expression varies as the x varies.&nbsp;<\/p>\n\n\n\n<p class=\" eplus-wrapper\">Now let us consider an equation 2x + 6 = 12.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\" eplus-wrapper\">The variable x can take any value in an equation also. It may or may not satisfy the equation. If it does, it is called the solution of the equation.<\/p>\n\n\n\n<figure class=\"wp-block-table eplus-wrapper\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Value of

Variables and Independent variables.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full eplus-wrapper\"><img loading=\"lazy\" decoding=\"async\" width=\"620\" height=\"293\"

class=\"eplus-wrapper wp-block-heading\" id=\"2-dependent-variables\"><br>Dependent Variables<\/h2>\n\n\n\n<p class=\" eplus-wrapper\">The dependent variable is a variable whose value is determined by the quantity another variable takes.&nbsp;<\/p>\n\n\n\n<p class=\" eplus-wrapper\">For instance, in the equation y = 2x + 3, x can take any value, like 1, 2, 3. However, the value of y will depend on the value of x. So, if x = 1, y will become 5, and if x = 2, y will become 7, and so on. Therefore, y is called the dependent variable and x is called the independent variable.<\/p>\n\n\n\n<figure class=\"wp-block-table eplus-wrapper\"><table class=\"wj-table-class\"><tbody><tr><td><strong>Independent Variable, <\/strong><strong>x<\/strong><\/td><td><strong>Dependent Variable, <\/strong><strong>y<\/strong><strong> = 2<\/strong><strong>x<\/strong><strong> + 3<\/strong><\/td><\/tr><tr><td>0<\/td><td>3<\/td><\/tr><tr><td>1<\/td><td>5<\/td><\/tr><tr><td>2<\/td><td>7<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"eplus-wrapper wp-block-heading\" id=\"3-independent-variables\">Independent Variables<\/h2>\n\n\n\n<p class=\" eplus-wrapper\">An independent variable in an algebraic equation is one whose values are unaffected by changes. If an algebraic equation has two variables, x, and y, and each value of x is related to any other value of y, then x is an independent variable, and y is a dependent variable.<\/p>\n\n\n\n<p class=\" eplus-wrapper\">For instance, in the equation y = 2x, x can take any value. Hence, it is the independent variable in the equation.<\/p>\n\n\n\n<p class=\" eplus-wrapper\"><strong>Conclusion<\/strong><\/p>\n\n\n\n<p class=\" eplus-wrapper\">Variables are a very important concept if you want to understand algebra.
