See a solution process below:

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

#4a + b + a - 4b#

Next, group like terms:

#4a + a + b - 4b#

Now, combine like terms:

#4a + 1a + 1b - 4b#

#(4 + 1)a + (1 - 4)b#

#5a + (-3)b#

#5a - 3b#
