Use Gauss-Jordan reduction of (A:I) to find A^-1.
The matrix is: 1 1 0/1 1 1/0 2 1 (ie 3x3 matrix)
I know you add the matrix on the right side with the diagonal 1's. I keep getting confused as to what I have to do. For example, I tried (Row3*-1/2)+row 1, then did (Row 1*2)+Row 2 and now I'm stuck. Help would be greatly appreciated!
