    The answer is -72.
    You should have made the denominators alike so that you could subtract the fractions easier.

    p/3-3p/8=3
    8p/24 - 9p/24 = 3
    -p/24 = 3
    -p= 3(24)
    -p= 72
    -p/-1 = 72/-1
    p=-72

    Easier way ...

    multiply each term by the LCD, which is 24, so

    8p - 9p = 72
    -p = 72
    p = -72
