    (2, 7) is the correct ordered pair.

    Step-by-step explanation:

    5x + 3y = 31

    2x + 3y = 25 Subtract to eliminate the y variable:

    3x = 6

    x = 6/3

    x = 2.

    Substitute x = 2 in the first equation:

    5*2 + 3y = 31

    3y = 31-10 = 21

    y = 21/3

    y = 7.

    Check the result by substituting for x and y in the second equation:

    2 (2) + 3 (7) = 25

    4 + 21 = 25

    25 = 25.
