Overview<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Linear Equation in One Variable is defined as an equation that consists of one variable having order 1 at the max. It is usually represented in the form of \u201cQx + r = 0\u201d, where \u2018x\u2019 represents the variable value. This equation will have the same values on the right and the left sides giving only one solution. Let us understand the few forms of Linear Equation in One Variable below \u2013<\/p>\n<p dir=\"ltr\">7x = 1<\/p>\n<p dir=\"ltr\">77x \u2013 1= 0<\/p>\n<p dir=\"ltr\">5x + 7 = -24<\/p>\n<p dir=\"ltr\">\u2018Q\u2019 and \u2018R\u2019 are the real numbers, also both these\u00a0 \u2018Q\u2019 and \u2018R\u2019 numbers are not equivalent to zero.<\/p>\n<p dir=\"ltr\">Hence, the formula of the linear equation \u2013 Having only one variable can be represented as Qx + R = 0.<\/p>\n<p dir=\"ltr\">You have to follow the basic three steps to solve any \u201cLinear Equations having One Variable\u201d.<\/p>\n<ol>\n<li dir=\"ltr\">Change the fractional units by making use of the LCM method.<\/li>\n<li dir=\"ltr\">Simplify the left and the right sides of the given equation.<\/li>\n<li dir=\"ltr\">Extract the variable.<\/li>\n<li dir=\"ltr\">Finally, just verify your solution.<\/li>\n<\/ol>\n<h3><span class=\"ez-toc-section\" id=\"steps-to-solve-the-linear-equations\"><\/span>Steps To Solve The Linear Equations<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p dir=\"ltr\">Let us consider an equation \u2013 3x \u2013 10 = -5x + 17\u00a0<\/p>\n<ol>\n<li dir=\"ltr\">\n<p dir=\"ltr\">Bring all the variables to one side \u2013 either left or either right, i.e., transposing.
