How do you solve this (preferably using Gaussian Elimination)
x+2y-3z+w=-2
3x-y-2z-4w=1
2x+3y-5z+w=-3

I thought you needed as many equations as variables to solve these.

Yeah you don't have enough info. It's degenerate. It reduces to:

x - z - w = 0
y - z + w = -1

For any value of w, this gives a straight line in 3d space. Sweeping through a range of w gives a nicely angled surface.
