    x = - 4

    Step-by-step explanation:

    2x+4 (2x+7) = 3 (2x+4)

    2x + 8x + 28 = 6x + 12

    10x + 28 = 6x + 12

    4x = - 16

    x = - 4

    x = - 4

    Step-by-step explanation:

    2x+4 (2x+7) = 3 (2x+4)

    Distribute

    2x+8x + 28 = 6x + 12

    Combine like terms

    10x + 28 = 6x + 12

    Subtract 6x from each side

    10-6x+28 = 6x + 12 - 6x

    4x + 28 = 12

    Subtract 28 from each side

    4x+28-28 = 12-28

    4x = - 16

    Divide each side by 4

    4x/4 = - 16/4

    x = - 4
