This document provides a system of linear equations and shows the steps to solve it. It begins with two initial equations (1) 2x+2y=-6 and (2) 1x-3y=5. It then performs elimination steps by multiplying and adding the equations until it isolates the variables and reaches the solutions of x=-2 and y=-2.
