For the second one then we'd have an equation for each.. type of work? Okay then each variable is for a different chair..
x + 1.5y + 1.5z = 41
1.5x + 2.5x + 3z = 70
x + 2y + 3z = 58
The rref'd matrix I get is:
| 1 0 -3 -10|
| 0 1 3 34|
| 0 0 0 0 |

In rref form the left side of the matrix should be an identity matrix.
