**Dr. Jane**, Wednesday, March 13, 2013 at 2:08pmI hope your other one didn't need matrices because..I did it the other way.

4 -1 -3 8

2 2 -1 3

6 1 -3 2

You want to manipulate the rows so that in the end, you end up with

1 0 0 a where a = the value for x

0 1 0 b where b = the value for y

0 0 1 c where c = the value for z.
