Hello jedimaster700In your first post, you said that the question talked about collecting 'like terms'. You obviously aren't sure what this means. and are not like terms, so you can't simplify them in the way you're trying to do here.
You need to find out what 'like terms' means. Here's a web-site that might help: BBC - GCSE Bitesize - Re-arranging symbols
Best of luck!
