Answer:
x = 3, y = -2, and z = 4
Step-by-step explanation:
x + y + z = 5 -2x - 3y + 2z = 8
3x - y - 2z = 3 x + y + z = 5....multiply by 3
---------------------add ----------------------------
4x - z = 8 -2x - 3y + 2z = 8
3x + 3y + 3z = 15
--------------------------- add
x + 5z = 23
4x - z = 8
x + 5z = 23....multiply by -4
---------------------
4x - z = 8
-4x - 20z = - 92 (result of multiplying by -4)
------------------------add
-21z = - 84
z = -84/-21
z = 4 <=====
4x - z = 8 x + y + z = 5
4x - 4 = 8 3 + y + 4 = 5
4x = 8 + 4 y + 7 = 5
4x = 12 y = 5 - 7
x = 12/4 y = -2 <====
x = 3 <====
Answer: -2
