Answer:
-12
Step-by-step explanation:
Let's replace that blank with x for now ;)
x - (-5) = -7
First, let's change that -(-5) to +5 because subtracting negatives is the same as adding.
x + 5 = -7
Subtract five from each side.
x + 5 = -7
-5 -5
x = -12
So then we change that x back to the blank and fill it in with -12.
