Answer:

Your answer of
-(39)/(8y) is correct

Explanation:

We begin with the expression:
-(4)/(y) +(-(7)/(8y) )

First, we need to find a common denominator, which in this case would be 8y.

To make the first term have a denominator of 8y, we must multiply it by
(8)/(8)


-(4)/(y)((8)/(8)) +(-(7)/(8y) )\\\\-(32)/(8y) +(-(7)/(8y) )

Now we can add them to get our final answer.


-(39)/(8y)
