b. 0
c. -6***
d. 3

did you actually try x=-6 to see whether you get the same y for both equations?
-3 x + 6 y = 18
- x + 6 y = 18
-------------------subtract
-2 x = 0
x = 0
y = 3
So I get x = 0
- x + 6 y = 18
-------------------subtract
-2 x = 0
x = 0
y = 3
So I get x = 0
so is the answer 0?
yes the answer is 0 ,
send the x to left side in the second equation and subtract both equation you get y =3
now put it in any of the equation you get the x value '0'.
