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