Question

Use Gaussian elimination to find the complete solution to the system of equations, or state that none exists.

3x - 2y + 2z - w = 2
4x + y + z + 6w = 8
-3x + 2y - 2z + w = 5
5x + 3z - 2w = 1

Answer 1

just put them in standard form

ax + by +cz + dz= 0

then do regular elimination

Answer 2

dw*

Answer 3

its just a long process

Answer 4

Ah, I see. Doesn't it need to be converted to a matrice of some sort?

Answer 5
