Solving Systems of Equations

The video tutorial explains how to solve systems of equations using the comparison method. It begins with setting up the equations and isolating variables. The tutorial then demonstrates solving for x by equating the right-hand sides of the equations. After finding x, the video shows how to substitute it back into one of the original equations to find y. The tutorial concludes with verifying the solution by checking that the values satisfy both equations.
