    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?

    How about 3?
    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.
