SV #5: Unit J Concept 3-4 (finding values using matrices)

Matrices can be very confusing to solve. First we have to make sure we simplyify the equations before moving on. Also, make sure that you copy down the correct COEFFICIENTS because if one value is wrong, the entire solution is. The other tricky part is canceling out to get zeroes and ones because it although they are simple steps, it's easy to make a mistake.
