    x=-6

    Step-by-step explanation:

    2 (x+9) = 4 (x+7) + 2

    Distribute

    2x+18 = 4x+28+2

    Combine like terms

    2x+18 = 4x+30

    Subtract 2x from each side

    2x-2x+18 = 4x-2x+30

    18 = 2x+30

    Subtract 30 from each side

    18-30 = 2x+30-30

    -12 = 2x

    Divide each side by 2

    -12/2 = 2x/2

    -6 = x
