The two main methods for solving a system of linear equations are substitution and combination (sometimes referred to as elimination by addition). Substitution is the most straightforward method for solving systems, and it can be applied in every situation.Here we talk about how to solve a 2x2 system of equations using both substitution and elimination.

This is a method of solving systems of equations. Example: 2x+3y=8 5x+3y=11 If you subtract the two you are left with -3x+0y=-3 Therefore x must equal 1 and through substitution you 2(1)+3y=8 ...
