    Answer with Step-by-step explanation:

    a. 5x = - 65

    Dividing both sides by 5, we get

    x = - 13

    b. 40 + x = - 5

    subtracting 40 on both sides, we get

    x = - 45

    c. 120 = 6x

    dividing by 6 on both sides, we get

    x = 20

    d. 6 = z : 14

    Multiplying both sides by 14, we get

    z = 84

    e. 11y + 20 = 64

    11y = 44

    y = 4

    f. 6x + 20 = - 4

    6x = - 24

    x = - 4

    g. 3y - 11 = - 32

    3y = - 21

    y = - 7

    h. x : 16 = 3

    Multiplying both sides by 16, we get

    x = 48
