    Answer:

    The answer to your question is x = -1

    Step-by-step explanation:

    Data

    f(x) = 2(x + 6) – 4

    f(x) = 6

    Process

    1.- Equal the function to 6

                 6 = 2(x + 6) – 4

    2.- Expand

                 6 = 2x + 12 – 4

    3.- Simplify like terms

                 6 = 2x + 8

    4.- Substract 8 in both sides

                 6 – 8 = 2x + 8 – 8

    5.- Simplify

                 – 2 = 2x

    6.- Divide both sides by 2

                -2/2 = 2x/2

    7.- Simplify

                -1 = x
