Hi,

I have been trying to solve this matrix for a while now, I don't get what I am doing wrong. I always end up having 2-3 full pages with an ending result that doesn't work at all.

Here is my matrix:

Anyone could help me solve the matrix ?Code:`(2 -1 3 4 | 9)`

(1 0 -2 7 | 11)

(3 -3 1 5 | 8)

(2 1 4 4 | 10)

Thanks so much
