Add -6z to both sides and you get 28 = 15z - 2
Then add the 2 to both sides and you get 30 = 15z
Divide 15 on both sides and get 2 = z

Use Gaussian elimination to find the complete solution to the system of equations, or state that none exists. Show your work. 4x-y+3z = 12 x+4y+6z =-32 5x+3y+9z = 20
