RS Aggarwal Solutions for Class 8 Chapter 8 includes “Linear Equation”, an Equation having the maximum order of 1 is known as a Linear equation (e.g. 3x+5=0). In mathematics, a linear equation is an equation that may be put in the form where are the variables, and are the coefficients, which are often real numbers. The coefficients may be considered as parameters of the equation and maybe arbitrary expressions, provided they do not contain any of the variables. Linear Equation deals with the definition of an equation, rules for solving a linear equation, how to do transposing and also about cross multiplication.
