No IMO these two are not the same as x/y-x can have two meanings

1) x/y-x = x/(y-x)

2) x/y-x = (x/y)-x

Usually when the question will come on the GMAT it will be more clear on what is it actually asking.

is x/y-x same as (x/y)-x?

You are wrong. If it were meant to be x divided by y - x, it would be written as x/(y - x), with parentheses around y - x. x/y - x can only mean (x/y) - x.

Math notation is precise and cannot depend on subjective gaps or spacing.
