Hi there! ~

To start off our equation we have (as listed in the question)

(y)/(-4) + 5 = 15

First we need to simplify, and to do so we are going to replace y with -1 as shown here;


(-1)/(4) y + 5 = 15

Now we subtract 5 from both sides.


(-1)/(4) y + 5 - 5 = 15 - 5

Now our next, and final step is to multiply both of our given sides by;
(4)/(-1)


( (4)/(-1) ) * ( (-1)/(4)y ) = ( (4)/(-1) ) * (10)

Leaving us with our final answer of y = -40.
Therefore, D.
