Question

solve for y.
4y + 2y - 18 = -72
simplify your answer as much as possible.
y = \boxed{}

Explanation:

Step1: Combine like terms

$4y + 2y = 6y$, so the equation becomes:
$6y - 18 = -72$

Step2: Isolate the term with y

Add 18 to both sides:
$6y - 18 + 18 = -72 + 18$
$6y = -54$

Step3: Solve for y

Divide both sides by 6:
$\frac{6y}{6} = \frac{-54}{6}$

Answer:

$y = -9$
