    Are you sure you wrote down the problem correctly?

    Let the number of apples bought be 3n,\ 0 \leq n \leq 5.

    Then the number of oranges bought is 5(5-n).

    So there are several different correct answers.

    If n= 0, he bought no apples and 25 oranges.

    If n= 1, he bought three apples and 20 oranges, etc.
