    x = - 1/2

    Step-by-step explanation:

    4 (x + 3) = 9x + 16 + 3x

    Distribute the 4

    4x + 12 = 9x+16+3x

    Combine like terms

    4x+12 = 12x+16

    Subtract 4x

    4x-4x+12 = 12x-4x+16

    12 = 8x+16

    Subtract 16

    12-16 = 8x+16-16

    -4 = 8x

    Divide by 8

    -4/8 = 8x/8

    -1/2 = x
