    The equivalent expression is n = 9/7

    Step-by-step explanation:

    Combining like terms and simplifying, we have:

    1/7 - 3 (3/7n-2/7)

    1/7 - 9/7n + 6/7

    7/7 - 9/7n

    1 - 9/7n

    7n - 9 (Multiplying both terms by 7n)

    7n - 9 = 0

    7n = 9

    n = 9/7

    The equivalent expression is n = 9/7
