Question

solve for y.
20 = - 4y + 2(y + 5)
simplify your answer as much as possible.
y =

Explanation:

Step1: Expand the expression

$20=-4y + 2y+10$

Step2: Combine like - terms

$20=(-4y + 2y)+10$
$20=-2y + 10$

Step3: Isolate the term with y

Subtract 10 from both sides:
$20-10=-2y+10 - 10$
$10=-2y$

Step4: Solve for y

Divide both sides by - 2:
$y=\frac{10}{-2}$
$y=-5$

Answer:

$y = - 5$
