See a solution process below:

First, expand the terms within parenthesis by multiplying each term within the parenthesis by the term outside the parenthesis:

#2n - color(red)(7)(n - 8)#

#2n - (color(red)(7) xx n) - (color(red)(7) xx -8)#

#2n - 7n - (-56)#

#2n - 7n + 56#

Now, combine like terms:

#(2 - 7)n + 56#

#-5n + 56#
