Question

_+(-8)=-7 what’s the blank?

Answer 1

Answer:+1

Step-by-step explanation: We can substitute the blank as x which will become x-8=-7.

Now our goal is to isolate the x value so we will move over the -8 which will become +8 from crossing over the equal sign.so x=-7+8. The answer to x which is the blank space is +1.
