Answer:
22
Step-by-step explanation:
You can substitute a with 15. So now, the equation is 2(15 - 5) + 2.
We can use PEMDAS to solve this equation now. Since the P is first in PEMDAS, we have to solve what's inside the parentheses first. 15 - 5 would be 10. So now the equation is 2(10) + 2.
There's no more to solve in the parentheses, so we can move on to multiplication. 2(10) would be 20. So now the equation is 20 + 2.
Add 20 + 2 and you get 22. Hope that helps!
