Hi

I'm supposed to solve this matrix equation by GaussJordan elimination and I find it very difficult to see and carry out the row operations mainly because of the z's. If someone is able to help me I would truly appreciate it.

zx1 + x2 + x3 = 1

x1 + zx2 + x3 = 1

x1 + x2 + zx3 = 1

z has a real value.
