Using substitution on a basic system of equations problem

The video tutorial explains solving inequalities using substitution. It begins by introducing the concept of substitution, where values are substituted into variables in equations. An example problem is solved to demonstrate this method. The tutorial then covers solving equations with given values for variables and discusses systems of equations, highlighting how to find solutions that satisfy multiple equations simultaneously.
