Question

Type the integer that makes the following subtraction sentence true:

– 4 = -12

Answer 1

I'll do something similar to this, and I challenge you to do this on your own!

<something>-7=-34
Making that something equal to x, we have x-7=-34. Adding 7 to both sides using the addition property of equality (and to separate the x), we have
-34+7=x=-27

Good luck, and feel free to ask with any further questions!
