#5b+14#

Explanation:

In this problem, the parenthesis are unnecessary, because we're not multiplying.

Our like terms are going to be those with variables, and the constants, respectively.

We can add the #2b# and #3b# to get #color(blue)(5b)#, because they both have the same variable.

We can add #5# and #9# because they both have no variable. We get #color(blue)(14)#.

We get #5b+14#. This cannot be simplified further because one term has a variable, and the other one doesn't.
