Question
$$6x-2(x+12) = 0$$
Answer
$$ x = 6 $$
Explanation
$$ \begin{aligned} 6x-2(x+12) &= 0&& \text{simplify left side} \\[1 em]6x-(2x+24) &= 0&& \\[1 em]6x-2x-24 &= 0&& \\[1 em]4x-24 &= 0&& \text{ move the constants to the right } \\[1 em]4x &= 24&& \text{ divide both sides by $ 4 $ } \\[1 em]x &= \frac{24}{4}&& \\[1 em]x &= 6&& \\[1 em] \end{aligned} $$
