How to Math - Solving a system of equations by using substitution

The video tutorial explains how to solve systems of equations using the substitution method. It begins with an introduction to systems of equations and the concept of solutions. The tutorial then demonstrates the substitution method with two example problems, showing how to find the intersection points of the equations. The process involves substituting one equation into another to eliminate variables and solve for the unknowns. The video emphasizes understanding the equality of equations at intersection points and provides a clear, step-by-step approach to solving these problems.
