So I guess when you are doing homework, then, you are up to no good?
Anyways,
{x - [f - (-x)] + [x - f]} - 3x
since there is no equal sign, I guess you're just supposed to simplify.
Use PEMDAS for order of operations:
{x - [f + x] + [x - f]} - 3x
{x - f - x + [x - f]} - 3x
{x - f - x + x - f} - 3x
-2f + x - 3x
-2f - 2x
All of the different bracket styles are equivalent in this case.
Their just used to keep you from going cross-eyed looking at:
(x - (f - (-x)) + (x - f)) - 3x
which means exactly the same thing, but some think it's harder to read.
