Question

Solve the system. Find X, Y, and Z.

Answer 1

Solve the system. Find X, Y, and Z.
6x-y+3z=5
x+3y-z=-1
3x+3y=4z
This is Equation 4 and 5
3x-10y=2 *9 > -27x+90y=-18
-x-9y=11 *10>=10x-90y=110
37x=92
X=? Can this be improper?

Answer 2

I tried eliminating z to equation 1 and 2 to get equation 4 and eliminating z to equation 2 and 3 to get equation 5
