    x=-3

    Step-by-step explanation:

    39 - 7X = - 4 (7X + 7) + 4

    Distribute

    39 - 7x = - 28x - 28 + 4

    Combine like terms

    39 - 7x = -28x - 24

    Add 28x to each side

    39 - 7x+28x = -28x+28x - 24

    39+21x=-24

    Subtract 39 from each side

    39-39+21x = - 24 - 39

    21x = - 63

    Divide by 21

    21x/21 = - 63/21

    x = - 3
