Start with the expanded array:
then using the tool provided, make row operations until you find the solution:
r2 = r2-3r1
r3 = r3+2r1
r2 = r2*(-1/13)
r1 = r1- r2*5
r3 = r3+ r2*-3
r3 = r3*13/168
r2 = r2- r3*22/13
r2 = r2+ r3*6/13
Here you have a reduced array an therefore the answers to each variable are on each row:
