I only know how to work matrix in the calculator.
You go to matrix-edit-1
Then you put 3X4 because that is the amount of numbers.
You plug in the numbers as:
1 3 -4 5
-2 -5 1 9
7 -1 -1 -2
Then you get out by pressing 2nd-mode
Next Go back into matrix-math-B:rref-matrix-1-enter
and you get x,y,z=515, -125, 0.
Hope it helped.
