Let's look at the first problem.

5 - x - x = -1

It means that you're subtracting a number twice from 5 and getting -1.
What number times 2 can be subtracted from 5 to get -1?

5 - 3 = 2
2 - 3 = -1

Or you can do it algebraically:
5-x-x = -1
6 = 2x
3 = x

If you post the answers to the other problems, we'll be glad to check them for you.
