    B

    Because when you distribute - 2 into (3x+6) you get - 6x - 12 and then when you do the same thing to 4 you get 4x + 28

    So then you subtract 4x to both sides and get - 10x and then you add 12 to both sides and you get 40

    After you divide - 10 to both sides and you get x < (with the line under) - 4
