Solving Systems of Linear Equations

The video tutorial explains how to solve a system of linear equations using the elimination method. It begins with an overview of different methods, then focuses on clearing fractions from equations by multiplying by the least common denominator. The tutorial demonstrates solving the system by making terms opposites and adding equations. It finds the solution as an ordered pair and verifies it graphically, ensuring the solution is correct.
