    Let the two numbers be x and y.

    The sum is 45, therefore

    x + y = 45 (1)

    The difference is 5, therefore

    x - y = 5 (2)

    Add equations (1) and (2).

    x + y + (x - y) = 45 + 5

    2x = 50

    x = 25

    From (1), obtain

    25 + y = 45

    y = 45 - 25 = 20

    Answer: 20 and 25
