You're welcome.

To collect like terms, you need to combine the terms that have the same variable raised to the same power. In this expression, we have 15p, -4p, 7q, and -9q.

First, let's combine the terms with the variable p:
15p - 4p = 11p

Next, let's combine the terms with the variable q:
7q - 9q = -2q

Now we can put the combined terms together:
11p - 2q

So the correct answer is 11p - 2q.

Well done, your answer is correct! Keep in mind to always check your solution by double-checking your work.
