    n = 7

    Step-by-step explanation:

    Let n represent the number. Then 3n = - n + 28, or 4n = 28.

    Dividing both sides by 4 yields n = 7.

    Check: "3 times a number" is 3n = 21

    The "opposite" of the number is - 7.

    If we add 28 to this "opposite," we get 21. This is correct: 21 = 21
