Question

solve for w.
$15w + 5w - 15w + 12 = -18$
$w = \square$

Explanation:

Step1: Combine like terms

$15w + 5w - 15w = 5w$, so the equation becomes:
$5w + 12 = -18$

Step2: Isolate the term with $w$

Subtract 12 from both sides:
$5w = -18 - 12$
$5w = -30$

Step3: Solve for $w$

Divide both sides by 5:
$w = \frac{-30}{5}$

Answer:

$w = -6$
