Using substitution to solve the system

The video tutorial explains how to solve a system of equations using the substitution method. It begins with an introduction to substitution, followed by setting up the equations. The instructor demonstrates how to substitute one equation into another and solve for the variables. The process involves simplifying the equations and finding the solution for both X and Y coordinates. The tutorial concludes with a recap of the steps involved in the substitution method.
