Question

This is a 2 Step process: answer to step 1: -1 , needing help with Step 2. Step 2: Find the restricted values of y, if any, for the given rational expression. Separate multiple answers with a comma.

Answer 1

EXPLANATION

Applying the conmutative rule: 4-4y = -4y + 4

Then factor -4y + 4:

= - (4y - 4)

$=\frac{-(4y-4)}{4y-4}$

Cancel the common factor 4y-4:

$=\frac{-1}{1}=-1$

The solution is (4-4y) / (4y-4) = -1
