Question

solve for y.
$9(y+4)=-9y+18$
simplify your answer as much as possible.
$y = \square$

Explanation:

Step1: Expand left-hand side

$9y + 36 = -9y + 18$

Step2: Add $9y$ to both sides

$9y + 9y + 36 = 18$
$18y + 36 = 18$

Step3: Subtract 36 from both sides

$18y = 18 - 36$
$18y = -18$

Step4: Divide by 18

$y = \frac{-18}{18}$

Answer:

$y = -1$
