none of those answers make any sense with the stated problem. You can dbl check them by working the backwards; plug the values into the equations and see if they are true.

x-2y+z=10 <-- (0,2,6) makes this false z=6 <-- (0,2,-6) makes this false 3x-2y+2z=8 <-- (0,-2,6) makes this false

x-2y+z=10 ; (-1,2,6)? -1 -2(2) +6 = 10 -1 -4 +6 = 10 -5 +6 = 10 .. FALSE
