SV 5 Unit J Concept 3-4: Matrices

Some things to notice is that to solve a matrices, you need to be able to get the triangle 0's and the 1's staircase. It is possible to use guess and check method, but that would take too long to do. Also, notice that it didn't take very long to solve because of the Gauss-elimination method which made it possible in 4 solutions. Also, remember to highlight the steps are you are doing so you don't get confused when doing a problem and make a mistake.
