## Homework Statement

3x + y -2z = 2

x - 2y +z = 3

2x - y -3z = 3

## Homework Equations

So when I put it in the matrix I get this:

[ 3 1 -2 2 ]

[ 1 -2 1 3 ]

[ 2 -1 -3 3 ]

## The Attempt at a Solution

My problem is that I have not really mastered the Gauss-Jordan elimination. So I don't know the exact rules as to how I can proceed with this. I don't know if there are any limitations as to how much I can multiply, substract, add rows to get to:

[ 1 0 0 ? ]

[ 0 1 0 ? ]

[ 0 0 1 ? ]

Thank you,
