Learn how to use substitution to solve a system of equations

The video tutorial explains how to solve a system of equations using the substitution method. It begins by identifying a variable with a coefficient of 1 or -1 to isolate. The instructor demonstrates solving for X, substituting the expression into another equation, and applying the distributive property to simplify. The tutorial concludes by finding the value of Y and verifying the solution algebraically, emphasizing the advantage of solving without graphing.
