    one thing is that it's a lot easier on the eyes if you don't use caps

    I edited your post for you :) anyway, we work here from the inside out so what is the first (innermost) operation?

    right, and there's not much we can do with that... so on to the next step we now look at it as\[3x-(-y-1)+2y\]do you know how to simplify this?

    i believe it is 3x+y+1+2y then 3x+2y+1

    x+{y-3-4x+2[3x-(-y-1)+2y]-3x} and we got that now to be x+{y-3-4x+2[3x+3y+1]-3x} so what is the innermost step we should do (careful on this one)

    almost.... and that can work, but we can make it even simpler the first thing to be done (the innermost operation) is to distribute the 2: 2[3x+3y+1]
