    simplification

    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

    \frac{1-(x-2)}{3}

    After distributing the negative, you'll have
    1 - x + 2 in the numerator.
