10y − 4z + w = 1

x + 4y − z + w = 2

3x + 2y + z + 2w = 5

−2x − 8y + 2z − 2w = −4

x − 6y + 3z = 1

**drwls**, Monday, May 13, 2013 at 5:21amI see more equations (5) than unknowns (4). The problem could be overdetermined.

The last equation is a simple combination of the third and fourth. So there is a solution, but you don't need the x − 6y + 3z = 1 equation to get it.
