    Step-by-step explanation:

    Plug in the values into each equation and solve.

    3x² - 2y

    3 (3) ² - 2 (5)

    3 (9) - 10

    27 - 10

    17

    2x² - 3y

    2 (3) ² - 3 (5)

    2 (9) - 15

    18 - 15

    3

    Now take the two values and subtract them from each other.

    17 - 3 = 14
