Answer:

The answer is -20

Step-by-step explanation:

X+8=-12

You subtract 8 from the left the the right side of the equal sign.

This leaves: X=-20

The reason is, when you subtract a negitive from a negitive you add them together given that they have the same + or - sign. In this case, they are both negitive.

12+8 equals 20

But because it's negive you have to add them together.
