simplify: 1/3 - (x-2)/3

(1-2)/3 - x

-(1/3) - x

I get -x-(1/3) but the online example states it should be (-x + 3)/3

is this correct and why?

They are correct.

Since you have common denominators, you can combine numerators. You'll get

After distributing the negative, you'll have

1 - x + 2 in the numerator. - April 1st 2011, 07:49 PMhansfordmc
