Скачать или смотреть 2.3 - Solving Linear Systems Using Technology

We’ll work through four examples of rewriting systems of linear equations as augmented matrices, then eight examples of solving these types of systems using your TI-84 graphing calculator. Once you understand how to input these into your calculator, it's significantly faster than solving by hand.

Use this video to review class material, take notes, and practice solving systems before your next assignment or quiz.
