What is the solution to the system of equations shown below 2x-y+z=4 4x-2y+2z=8 -x+3y-z+=5
1 answer:
Answer:
Step-by-step explanation:
2x - y + z = 4
4x - 2y + 2z = 8
-x + 3y - z = 5
2x - y + z = 4
-x + 3y - z = 5
x + 2y = 9
4x - 2y + 2z = 8
-2x + 6y - 2z = 10
2x + 4y = 18
x + 2y = 9
2x + 4y = 18
-2x - 4y = -18
2x + 4y = 18
0 =0
