How to solve a system of equation using substitution

The video tutorial explains how to solve a system of equations using the substitution method. It begins by identifying a variable to solve for, preferably one with a coefficient of one, to simplify the process. The tutorial demonstrates solving for this variable and substituting it into the other equation. The process involves using inverse operations and combining like terms to find the values of both variables. The tutorial concludes with a recap of the steps involved in solving systems of equations using substitution.
