When you are given multiple equations and multiple variables, a graphing calculator can be a lifesaver. New versions of the TI-84+ come with a pre-installed app the makes these problems a snap. This video lesson covers solving systems equations by the elimination, or linear combination method, before covering how to use the TI-84 plus to solve.
The lesson does require you to have the PLYSMT2 app installed on your TI-84. If you don’t have that app, you can download it free from the TI website. We’ll have a tutorial on how to install apps soon.
