Question
$$12+56y = -38+48y$$
Answer
$$ y = -\dfrac{25}{4} $$
Explanation
$$ \begin{aligned} 12+56y &= -38+48y&& \text{move the $ \color{blue}{ 48y } $ to the left side and $ \color{blue}{ 12 }$ to the right} \\[1 em]56y-48y &= -38-12&& \text{simplify left and right hand side} \\[1 em]8y &= -50&& \text{ divide both sides by $ 8 $ } \\[1 em]y &= -\frac{50}{8}&& \\[1 em]y &= -\frac{25}{4}&& \\[1 em] \end{aligned} $$
