Math tutorial for solving systems of equations using substitution

The video tutorial covers the substitution method for solving systems of equations in algebra. It begins with an introduction to the method, explaining why substitution is sometimes preferred over graphing. The instructor then outlines the steps to identify variables with coefficients of one or negative one, solve for these variables using inverse operations, and substitute them into other equations. The tutorial emphasizes simplifying and solving for the remaining variable, ultimately finding the solution as a coordinate point.

How do you solve for a variable after substituting it into the equation?

What is the final step after finding the value of one variable in a system of equations?
