solve for w. -9 + 8w = 9 + 10w w =

Explanation:

Step1: Move variable terms to one side

$$ \begin{align*} -9 + 8w&=9 + 10w\ 8w-10w&=9 + 9 \end{align*} $$

Step2: Simplify both sides

$$ \begin{align*} -2w&=18 \end{align*} $$

Step3: Solve for (w)

$$ \begin{align*} w&=\frac{18}{-2}\ w&=-9 \end{align*} $$

Answer:

(-9)
