Question
$$2x = 6(x-4)$$
Answer
$$ x = 6 $$
Explanation
$$ \begin{aligned} 2x &= 6(x-4)&& \text{simplify right side} \\[1 em]2x &= 6x-24&& \text{move the $ \color{blue}{ 6x } $ to the left side} \\[1 em]2x-6x &= -24&& \text{simplify left side} \\[1 em]-4x &= -24&& \text{ divide both sides by $ -4 $ } \\[1 em]x &= \frac{-24}{-4}&& \\[1 em]x &= 6&& \\[1 em] \end{aligned} $$
