    Answer:

    (12,-1)

    Step-by-step explanation:

    Plug in the x and y values into the equation to see if it gives you 14 and 9.

    Option 1:

    (1) – 2(12)

    1 – 24 = -23 Not it

    Option 2:

    (-1)-2(-12)

    -1 + 24 = 23 Not it

    Option 3:

    (12) – 2(-1)

    12 +2 = 14 Yes, but make sure with the second equation

    12 +3(-1)

    12 – 3 . Works

    Answer is (12,-1)
