Solving a system of equation with infinite solutions using substitution

The video tutorial explains how to solve a system of equations using the substitution method. It begins by introducing the concept of substitution and the given equations. The instructor demonstrates the process of substituting one equation into another to eliminate a variable, followed by solving and simplifying the resulting equation. The tutorial concludes by discussing the concept of infinite solutions, where the equations represent the same line on a graph.
