Solve the following system of equations:
2x−3y+z=32x - 3y + z = 32x−3y+z=3
6x−12y+4z=86x - 12y + 4z = 86x−12y+4z=8
−3x+6y−2z=6-3x + 6y - 2z = 6−3x+6y−2z=6
x+6y−7z=−2x + 6y - 7z = -2x+6y−7z=−2
2x+12y−14z=−42x + 12y - 14z = -42x+12y−14z=−4
4x+24y−28z=−84x + 24y - 28z = -84x+24y−28z=−8
x−2y+z=3x - 2y + z = 3x−2y+z=3
3x−6y+3z=93x - 6y + 3z = 93x−6y+3z=9
2x+5y−z=−62x + 5y - z = -62x+5y−z=−6
