Using elimination to solve a system

The video tutorial explains how to solve equations using the elimination method. It covers aligning variables and coefficients, using the least common multiple to adjust coefficients, and multiplying equations to facilitate elimination. The tutorial demonstrates eliminating variables through addition or subtraction and solving for the remaining variables.
