    B) 7

    Step-by-step explanation:

    Subtract 11 by both sides

    3x - 4 (x + 1) + 11 - 11 = 0 - 11

    Simplify

    3x - 4 (x + 1) = - 11

    Distribute 4

    3x - 4x - 4 = - 11

    Add 4 to both sides and combine like terms

    -x - 4 + 4 = - 11 + 4

    -x = - 7

    Divide both sides by - 1

    x = 7
