Answer:
43
Step-by-step explanation:
We can find an answer to this question by setting up an equation.
-31+x=12
x is the unknown amount we should add to -31 to obtain 12.
Now, to solve it for the variable, x, we need to add 31 to both sides.
Upon doing this we obtain.
x=43
∴, 43 should be added to -31 to get 12
