Answer:
10
Explanation:
I'm assuming here that your expression is equivalent to the one below:
In this case, we'll start by adding 9 and 15 to get 24. Now we have 24/3 + 2. 24/3 = 8, so now we have 8 + 2, and this is equal to 10.
And that's the simplified version of your expression.
Hopefully that helps! Let me know if you have any further questions.
