    Mary = 24

    Chau = 15

    David = 48

    Step-by-step explanation:

    The formula is

    Mary + Chau + David = 87

    And we know that

    Chau = Mary - 9

    David = Mary * 2

    So when we fill this in

    Mary + Mary - 9 + Mary * 2 = 87

    4Mary - 9 = 87

    4Mary = 96

    Mary = 24

    Chau = Mary - 9 = 15

    David = Mary * 2 = 48
