Question

What is -13=-h-7 step by step.?

Answer 1

Since it’s -7 you’re going to add seven to both sides so -7 and +7 cancel each other out then -13+ positive seven so -13+7 should be -6 then since there’s a one behind the eight today and it should basically just be six

Answer 2

We need to make h alone.
Add 7 to both sides to remove -7 from the right, and multiply both sides by -1 to make h positive. Doesn't matter which you do first.
Result:
6=h
h=6
