Answer:

-17

Explanation:

I will represent the question mark with the variable
x.


x - 11 + 12 = -16

To solve for
x, we need to isolate it.

To do this, subtract 12 from both sides.


x - 11 + 12= -16\\\underline{\textrm{ } \ \ \ \ \ \ \ \, -12} \ \, \, \, \, \ \underline{-12}\\x - 11 \ \ \ \ \ \: \ = -28

Then, add 11 to both sides.


x - 11 = -28\\\underline{\ \ \: + \, 11} \ \ \ \, \underline{+ \, 11}\\x \ \ \ \ \ \ \: = -17


x = -17

So, the integer that makes the equation true is -17.
