    B.

    no real solutions

    Step-by-step explanation:

    2 (x + 11) + 5x = 7x - 22

    Distribute

    2x+22 + 5x = 7x - 22

    Combine like terms

    7x + 22 = 7x-22

    Subtract 7x from each side

    7x-7x+22 = 7x-7x-22

    22 = - 22

    This is never true so there are no solutions
