Question
$$2(x+2)-6(x-4) = 0$$
Answer
$$ x = 7 $$
Explanation
$$ \begin{aligned} 2(x+2)-6(x-4) &= 0&& \text{simplify left side} \\[1 em]2x+4-(6x-24) &= 0&& \\[1 em]2x+4-6x+24 &= 0&& \\[1 em]-4x+28 &= 0&& \text{ move the constants to the right } \\[1 em]-4x &= -28&& \text{ divide both sides by $ -4 $ } \\[1 em]x &= \frac{-28}{-4}&& \\[1 em]x &= 7&& \\[1 em] \end{aligned} $$
