See a solution process below:

First, remove all of the terms from parenthesis. Be careful to handle the signs of each individual term correctly:

#m + 2n + n - 6m + 2m - 3n#

Next, group like terms:

#m - 6m + 2m + 2n + n - 3n#

Now, combine like terms:

#1m - 6m + 2m + 2n + 1n - 3n#

#(1 - 6 + 2)m + (2 + 1 - 3)n#

#-3m + 0n#

#-3m#
