Pre-Calculus - Solve a system of equations using a Ti-83 or Ti-84 calculator

This video will run through the basics of solving a system of equations using a calculator from the Ti-83 and Ti-84 family of calculators. In the video I use a Ti-84 CE, but the menu system is identical to older calculators. Remember to carefully interpret your solution when you have your solved matrix.
