    (-14, - 33)

    Step-by-step explanation:

    Note that y = x + 9. Substitute (x + 9) for y in the first equation, obtaining:

    2x - (x + 9) = - 14, or

    x + 19 = - 14, or x = - 33.

    Now substitute - 33 for x in the second equation and find y:

    y = (-33) + 9 = - 14

    The system solution is (-14, - 33).
