Video lesson: Solving a system of equations with the TI-nspire

When you are given multiple equations and multiple variables, a graphing calculator can be a lifesaver.  Since the introduction of OS 2.0 on the TI-nspire, this is something you can do easily on your calculator.  


This video lesson review the “elimination” or “linear-combination” method before going on to explain how to solve these problems on your nspire.  If you don’t yet have OS 2.0, you’ll need to get it for this lesson.  If you’re not sure how to do the upgrade, you can watch my tutorial here.
