    A + s = 279

    s = 2a

    a + 2a = 279

    3a = 279

    a = 279/3

    a = 93 < = = = adult

    s = 2a

    s = 2 (93)

    s = 186 ... students

    S=2a

    a+s=279, using a from above in this equation gives you:

    a+2a=279 combine like terms on left side

    3a=279 divide both sides by 3

    a=93

    So 93 adult tickets were sold.
