Answer:
14
Step-by-step explanation:
It says 'Evaluate (y - 9) + (3 + x), when y = 15 and x = 5'. 
So we'd put 15 in y's place. It'll look like this (15 - 9). 
Then we'd put 5 in x's place. It'll look like this (3 + 5).
You subtract (15 - 9) which equals 6. And you'd add (3 +5) which equals 8. You add 6 + 8 together since those are your answer for the parentheses. Your final should be 14. Hopefully this helped!
