    The value of x in the equation is 7

    Step-by-step explanation:

    To find the value of x, we will follow the steps below:

    8+4 = 2 (x-1)

    open the parenthesis on the right-hand side of the equation by multiply x-1 by the 2

    8+4 = 2x - 2

    12 = 2x - 2

    Add 2 to both-side of the equation

    12 + 2 = 2x - 2 + 2

    14 = 2x

    Divide both-side of the equation by 2

    14/2 = 2x/2

    7 = x

    x = 7

    The value of x in the equation is 7
