  1. 2(9n - 1) + 7(n + 6) = -60

    using distributive property

    (2)(9n) - (2)(1) + (7)(n) + (7)(6) = -60

    18n - 2 + 7n + 13 = -60

    rearrange the terms

    18n + 7n - 2 + 42 = -60

    25n + 40 = -60

    subtract 40 from both sides

    25n = -60 - 40

    25n = -100

    divide both sides by 25

    n = -4
