    2n + 28 = 48

    Step-by-step explanation:

    - perimeter is 48 ft

    - length is 14 ft

    formula for perimeter of a rectangle:

    P = 2L + 2W

    If you substitute in the values we know, then you get:

    48 = 2 (14) + 2W

    48 = 28 + 2W

    W = n, so it's the same as this:

    48 = 28 + 2n

    And if you switch them around, you get this:

    2n + 28 = 48
