Answer:
-5
Step-by-step explanation:
First, distribute the 2 to the 3, -9, and 5. You will get 6 + 6 - 18 + 10 + (-9). Then, you can start from the beginning and work through combining the terms. The original equation is in bold after every step. 
6 + 6 - 18 + 10 + (-9)
6+6 = 12
12 - 18 + 10 + (-9)
12-18 = -6
- 6 + 10 + (-9)
-6 + 10 = 4 
4 + (-9) 
4 - 9 = -5
