    2 (20 - 27 n)

    Step-by-step explanation:

    Simplify the following:

    7 - 3 (9*2 n + (3 n + 8 n) / (-n))

    3 n + 8 n = 11 n:

    7 - 3 (9*2 n + (11 n) / (-n))

    (11 n) / (-n) = n/n*11 / (-1) = 11 / (-1):

    7 - 3 (9 2 n + 11 / (-1))

    Multiply numerator and denominator of 11 / (-1) by - 1:

    7 - 3 (9 2 n + - 11)

    9*2 = 18:

    7 - 3 (18 n - 11)

    -3 (18 n - 11) = 33 - 54 n:

    33 - 54 n + 7

    Add like terms. 7 + 33 = 40:

    40 - 54 n

    Factor 2 out of 40 - 54 n:

    Answer: 2 (20 - 27 n)
