The answer is -63. However, it's important that you know how to do this so you can solve similar problems in the future. (x represents the #) Set up an equation. 51+x= -12. You want to have the variable on 1 side and all other numbers on the other side. So subtract 51 from both sides to get x= -12-51. x= -63

Solve the number for x.
51x=-12
-51 -51
x=-63

51 plus 12 makes 63 so I guess -63 plus 51 would make -12 but I am terrible at math.

If the number is x.
x+51=-12
x=-12-51=-63
The number is -63

51 + x = -12
51 + x -51 = -12 -51
x = -63

x+51= -12
-51 -12
you subtract -51 from both sides
the = +51 and - 51 cancel out on the left side
so it is just x= -12 -51
x= -63
because you add two negatives and keep the sign
