Answer: -4

Explanation:

Two unlike signs automatically means to just subtract. So, now it looks like 8-12.
Subtract the smaller number from the larger number, 12-8, which equals to four.
But keep the sign of the larger value, which was 12, and twelve had a negative sign in he beginning, so 8+(-12) = -4.

Hope this helps, please mark as brainliest!
