SOLVING A SYSTEM OF LINEAR EQUATIONS BY SUBSTITUTION
The graphing method for solving a system of linear equations only works well when the ordered pair solution are only integers. Therefore, we need an algebraic method for solving systems of equations. There are two algebraic methods that we can use to solve a system of equations. These are:
I. The Substitution Method
II. The Elimination Method.
This e-book describes the process of solving linear equations by using the Elimination Method
