Short Answer B
Remark
I'm going to interpret this as
![\frac{8(y + 5)}{[3*(3y + 7)]}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%28y%20%2B%205%29%7D%7B%5B3%2A%283y%20%2B%207%29%5D%7D%20)
Step One
Before removing the brackets, the easiest way to start is to substitute for y.
![\frac{8(3 + 5)}{[3*(3*3 + 7)]}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%283%20%2B%205%29%7D%7B%5B3%2A%283%2A3%20%2B%207%29%5D%7D%20)
Step Two
Combine what's inside the brackets.
![\frac{8(8)}{[3*(9 + 7)]}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%288%29%7D%7B%5B3%2A%289%20%2B%207%29%5D%7D%20)
![\frac{8(8)}{[3*(16)]}](https://tex.z-dn.net/?f=%20%5Cfrac%7B8%288%29%7D%7B%5B3%2A%2816%29%5D%7D%20)
Step 3
Do the multiplication in both brackets in the top and bottom
Step 4
Reduce by dividing both top and bottom by 16.
The answer should be 4/3
