Use substitution to solve a system of equations with variables n and m

The video tutorial covers solving systems of equations using substitution. The teacher emphasizes the importance of using substitution for quizzes and explains how to identify variables with a coefficient of 1 for easier solving. The process involves solving for one variable and substituting it into another equation, applying the distributive property, and finding the final solution. The tutorial also addresses common questions and clarifies the steps involved.
