See the solution process below:

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

#7a + 3b - 3a - 8a + 7b - 5d#

Next, group like terms:

#7a - 3a - 8a + 3b + 7b - 5d#

Now, combine like terms:

#(7 - 3 - 8)a + (3 + 7)b - 5d#

#-4a + 10b - 5d#
