I guess for us to help you we probably need to understand your problem better.

For example

1) If y=x+8 and x=5
can you tell me what y will be?

if you can do this one easily, perhaps you could tell us one that you don't quite understand.
We really do want to help you.

More like Reinout's explanation, his made things a little clearer
