Solve
x+y+z=10
−2x−2y−z=−32
3x−2y+2z=−8
Enter your answer, in the form (x,y,z).
x + y + z = 10,
2x + 2y + 2z = 20
2x + 2y + 2z = 20
+ -2x - 2y - z = -32
__________________
z = -12
x + y - 12 = 10,
x + y = 22,
3x + 3y = 66
3x - 2y - 24 = -8,
3x - 2y = 16
3x + 3y = 66
- 3x - 2y = 16
_________________
5y = 50
y = 10
x + 10 - 12 = 10,
x = 12
(x. y, z) = (12, 10, -12)
