Question
$$3(c+3) = 2(c+20)$$
Answer
$$ c = 31 $$
Explanation
$$ \begin{aligned} 3(c+3) &= 2(c+20)&& \text{simplify left and right hand side} \\[1 em]3c+9 &= 2c+40&& \text{move the $ \color{blue}{ 2c } $ to the left side and $ \color{blue}{ 9 }$ to the right} \\[1 em]3c-2c &= 40-9&& \text{simplify left and right hand side} \\[1 em]c &= 31&& \\[1 em]c &= 31&& \\[1 em] \end{aligned} $$
