Answer 3

Let's solve the expression step-by-step:

1. Add 7 and (-8): 7 + (-8) = -1

2. Subtract 12 from the result: -1 - 12 = -13

3. Now, we have to deal with the double negative: -(-7) = 7 So, the expression becomes: -13 - (-7) = -13 + 7 = -6

4. Add 13 to the result: -6 + 13 = 7

5. Finally, subtract 20: 7 - 20 = -13

So, the final result is -13.
