I've been working on a practice set and this equation is giving me some trouble:

-(3/4x-1/3)+2x

The answer key says the answer is:

5/4x +1/3

I don't understand why the answer is stated as such. Shouldn't
the 5/4x be -5/4x because of the distributive property? Also,
shouldn't the 5/4x and 2x be multiplied by LCD 4? If someone could
write out the solution this would help me understand better.

Hello Dan

-(3/4x-1/3) +2x --> (-3/4x -- 1/3) + 2x --> -3/4x + 1/3 + 8/4x --> 5/4x + 1/3

Nicely Done. A+
