Question
$$53w+13 = 56w+16$$
Answer
$$ w = -1 $$
Explanation
$$ \begin{aligned} 53w+13 &= 56w+16&& \text{move the $ \color{blue}{ 56w } $ to the left side and $ \color{blue}{ 13 }$ to the right} \\[1 em]53w-56w &= 16-13&& \text{simplify left and right hand side} \\[1 em]-3w &= 3&& \text{ divide both sides by $ -3 $ } \\[1 em]w &= -\frac{3}{3}&& \\[1 em]w &= -1&& \\[1 em] \end{aligned} $$
