Using substitution to solve a system when multiple variables have a coefficient of 1

The video tutorial covers solving systems of equations using the substitution method. It begins with an introduction to substitution and elimination methods, then focuses on substitution. The teacher explains how to identify variables with a coefficient of 1, solve equations by substituting expressions, and provides an example problem. The tutorial concludes with a discussion on independent consistent systems, where the solution is a single intersection point.
