#### Answer

$y = \frac{-1}{9}$

#### Work Step by Step

Our goal is to isolate y. To accomplish this we will first add 2y to both sides to get all of the y's on one side:
7y + 4 = 3 - 2y
9y + 4 = 3
We will then isolate y by subtracting 4 from both sides and then dividing both sides by 9:
9y + 4 = 3
9y = -1
$y = \frac{-1}{9}$
