SV#5: Unit J Concept 3-4: Matrices

I apologize in advanced for the video being choppy and echo-y. Also, when the calculator appears, that means that I am going over how to check your answers.

Be sure that when going over this video, you write down next to the matrix what you are doing to obtain row echelon form. Also, do not forget to not misplace negatives. Lastly, don't forget all the elementary row operations.
