    When expanded we get:

    3x - 8 + 2x + 5 - 4x - 8

    After collecting the like terms:

    3x + 2x - 4x - 8 + 5 - 8

    Now simplify (step by step)

    1) 5x - 4x - 8 + 5 - 8

    2) x - 8 + 5 - 8

    3) x - 16 + 5

    4) x - 11

    Therefore the answer equals (x - 11) which is option (A)
