See a solution process below:

Explanation:

First, remove all of the terms from parenthesis. Be careful to handle the signs of each individual term correctly (remember, minus a minus is a plus):

#5x - 1 + 9x + 5#

Next, group like terms:

#5x + 9x - 1 + 5#

Now, combine like terms:

#(5 + 9)x + (-1 + 5)#

#14x + 4#
