Solve the system of equations by using substitution

The video tutorial explains how to solve a system of equations using the substitution method. It begins by identifying which variable to solve for first, typically the one with a coefficient of one or easily isolated. The tutorial demonstrates substituting the solved variable into the second equation and using the distributive property to solve for the other variable. Finally, it shows how to find the values of both variables and interpret the solution as the intersection point of the graphs of the equations.

After finding the value of X, how do you find the value of Y?

What does the intersection of the two graphs represent in the context of solving the system of equations?
