Y + 3y + 5y = -18 what is the value of y

ANEK [815]

Answer:

y = -2

Step-by-step explanation:

Step 1: Combine like terms.

$(y+3y+5y)=-18$
$9y=-18$

Step 2: Divide both sides by 9.

$9y/9=-18/9$
$y=-2$

Step 3: Check if solution is correct.

$-2+3(-2)+5(-2)=-18$
$-2-6-10=-18$
$-18=-18$

Therefore, y = -2.
