SV#5: Unit J Concept 3-4: Solving three varibles systems with Gauss-Jordan elimination/matrices/row-echelon form/ back-substitution and solving non square systems

The viewer needs to pay special attention of dividing the original equations as much as possible. Also, the viewer need to pay special attention to correctly distributing the number to each applied row to get the new row. Lastly, the viewer needs to double check what they are plugging in for ref and rref because for ref you put the original equations and rref you put in the last matrix's number.
