adding/subtracting rational expressions with common denom.

if i have 4x/2x-5 - 2x/2x-5 and get 2x/2x-5, i cannot simplify to 1/-5, correct?

and 5x/3x-4 - 3x/3x-g=2x/3x-4 cannot simplify to x/3x-2, right?


thanks in advance.

nevermind, i reviewed my notes. i'm pretty sure i cannot simplify those anymore.
the first one would just be 2x/2x-5.
