Solving Systems of Equations

This video tutorial explains how to solve systems of equations using the equal value method. It begins with an introduction to systems of equations, highlighting the importance of finding solutions that satisfy all equations. The tutorial then details the equal value method, where expressions set equal to the same variable are equated to find the solution. The process of finding the point of intersection is demonstrated, followed by instructions on writing the solution as a coordinate. The video concludes with a call to practice solving systems and emphasizes the importance of expressing answers as coordinates.
