Answer 1

What's the question?

Answer 2

I need help solving them.

Answer 3

Posting a bunch of similar questions, and expecting somebody to do your homework for you, usually does not result in success.

I will show you how to do the first, you do the rest the same way.

-21=p-13
-21 + 13 = p - 13 + 13
-8 = p
p = -8

Answer 4

ok. thank you.

Answer 5

Here is how you do the first one. Just remember, you can do almost anything to an equation but do it to both sides.
-21=p-13
<b> You want the unknown on one side and everything else on the other. So we need to move the 13.
Add 13 to both sides.
-21+13 = p-13+13
combine terms
-8=p

The others are done essentially the same way.
For the last one,
3n=-27
Divide both sides by 3
3n/3 = -27/3
n=-9
Someone will be happy to check your work on the others.</b>
