SV #5: Unit J Concept 3-4: Solving Three Variable Systems (Matrix)

**Sorry everyone about the video! Something went
wrong with the downloading part of the video so that's why you can't 
watch it right side up. I apologize :(

    The viewer needs to pay attention to the rows and where each equation
best fits in which row. Remember, we are trying to get zero on a specific
row and term! Also, before you actually start the problem, it'll be easier
if you factor the equation before hand. Near the end of the matrix, the
viewer should have the stairstep of 1's (in this problem at least because
it is an consistent independent system). If you want to double check your
answer, you may use your graphing calculator to make sure if your answer
is correct. In this case, the viewer should use the Gauss-Jordan elimination
system on his or her graphing calculator. Thanks for watching!
