Question
$$9w-2 = -w-22$$
Answer
$$ w = -2 $$
Explanation
$$ \begin{aligned} 9w-2 &= -w-22&& \text{move the $ \color{blue}{ -w } $ to the left side and $ \color{blue}{ -2 }$ to the right} \\[1 em]9w+w &= -22+2&& \text{simplify left and right hand side} \\[1 em]10w &= -20&& \text{ divide both sides by $ 10 $ } \\[1 em]w &= -\frac{20}{10}&& \\[1 em]w &= -2&& \\[1 em] \end{aligned} $$
