Question

solve for y.
5y + 5 = -2(y + 8)
simplify your answer as much as possible.

Explanation:

Step1: Expand the right-hand side

$5y + 5 = -2y - 16$

Step2: Add $2y$ to both sides

$5y + 2y + 5 = -16$
$7y + 5 = -16$

Step3: Subtract 5 from both sides

$7y = -16 - 5$
$7y = -21$

Step4: Divide by 7 on both sides

$y = \frac{-21}{7}$

Answer:

$y = -3$
