Solving Systems of Linear Equations (Algebra Unit 9: Practice Problem 2)

In this lesson, we will solve 1 system of 2 linear equations. I will discuss why I chose elimination over substitution, how to solve it using elimination, and what the answer means. We will also look at a second approach to solving this problem using substitution. The lesson will conclude with a similar problem with solution for you to practice independently.
