Finite Math Help

alright, if you wanna actually know the steps that i took, here goes:
1) multiply row 1 by 3, row 2 by -4 and row 3 by 6.
2) row 1 + row 2 = new row 2
3) row 1 + row 3 = new row 3
4) multiply row 1 by -23, row 2 by 3, row 3 by 23.
5) row 1 + row 2 = new row 1
6) row 2 + row 3 = new row 3
7) your 3rd row should now look like: 798z = 1596, OR z = 2.
8) solve backwards from there.

repeat this logic for every problem, and you should be peachy keen. i miss this stuff... but i'll gladly give it up to change diapers and raise my kids right...
