Question 162605: If you could please help me I have four equations that i have to solve for w, x, y, and z. You had people ask about the three equations with three variables, but this one is a little tougher. The problem is:
2w-x+5y+z=-3
3w+2x+2y-6z=-32
w+3x+3y-z=-47
5w-2x-3y+3z=49
If you could please help me, I would GREATLY appreciate it.

You can put this solution on YOUR website!
2w-x+5y+z=-3
3w+2x+2y-6z=-32
w+3x+3y-z=-47
5w-2x-3y+3z=49
-----------------
Use any method you know to get:
w= 2
x=-12
y=-4
z= 1
