Question
$$2y+5 = 20y$$
Answer
$$ y = \dfrac{5}{18} $$
Explanation
$$ \begin{aligned} 2y+5 &= 20y&& \text{move the $ \color{blue}{ 20y } $ to the left side and $ \color{blue}{ 5 }$ to the right} \\[1 em]2y-20y &= -5&& \text{simplify left side} \\[1 em]-18y &= -5&& \text{ divide both sides by $ -18 $ } \\[1 em]y &= \frac{-5}{-18}&& \\[1 em]y &= \frac{5}{18}&& \\[1 em] \end{aligned} $$
