Ok, first you are going to combine like terms, therefore adding 3a + 2a. You'll get 5a, right? Of course.

Now your expression looks like this: 5a-%284a%2B7%29

Alright, you gotta get rid of that pesky little minus sign, so distribute it throughout the parenthesis.

5a%2B4a-7

Combine like terms again.

9a-7

And there's your answer.
