I also need work

Answer 1

Short Answer B
Remark
I'm going to interpret this as

`(8(y + 5))/([3*(3y + 7)])`

Step One
Before removing the brackets, the easiest way to start is to substitute for y.

`(8(3 + 5))/([3*(3*3 + 7)])`

Step Two
Combine what's inside the brackets.

`(8(8))/([3*(9 + 7)])`

`(8(8))/([3*(16)])`

Step 3
Do the multiplication in both brackets in the top and bottom

`(64)/(48)`

Step 4
Reduce by dividing both top and bottom by 16.


`( (64)/(16) )/( (48)/(16) )`

The answer should be 4/3
