Answer 2

Hi there! ~

To start off our equation we have (as listed in the question) 
$\frac{y}{-4} + 5 = 15$

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

$\frac{-1}{4} y + 5 = 15$

Now we subtract 5 from both sides.

$\frac{-1}{4} y + 5 - 5 = 15 - 5$

Now our next, and final step is to multiply both of our given sides by; $\frac{4}{-1}$

$( \frac{4}{-1} ) * ( \frac{-1}{4}y ) = ( \frac{4}{-1} ) * (10)$

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