What is the reduced row echelon form of this matrix?

Question

augmented matrix

[original matrix solution column
[12, 10, -6, -3, 7, 10 | a ]
-7, -6, 4, 7, -9, 5 | b ]
9, 9, -9, -5, 5, -1 | c ]
-4, -3, 1, 6, -8, 9 | d ]
8, 7, -5, -9, 11, -8 | e ]

.

Answer 1

I just plugged this into my calculator.

[1, 0, 2, 0, 2, 0 | 0
0, 1, -3, 0, -2, 0 | 0
0, 0, 0, 1, -1, 0 | 0
0, 0, 0, 0, 0, 1 | 0
0, 0, 0, 0, 0, 0 | 1 ]

Take it however you want.

Answer 2

Take a while to solve but to ans reduce echelon form

echelon form: only bottom half is Zeroed

--------
|1 # # |
|0 1 # |
|0 0 1 |
---------

reduced echelon: top and bottom are zeroed

--------
|1 0 0 |
|0 1 0 |
|0 0 1 |
---------
