Question
$$2(3x-1)-2(x+5) = 0$$
Answer
$$ x = 3 $$
Explanation
$$ \begin{aligned} 2(3x-1)-2(x+5) &= 0&& \text{simplify left side} \\[1 em]6x-2-(2x+10) &= 0&& \\[1 em]6x-2-2x-10 &= 0&& \\[1 em]4x-12 &= 0&& \text{ move the constants to the right } \\[1 em]4x &= 12&& \text{ divide both sides by $ 4 $ } \\[1 em]x &= \frac{12}{4}&& \\[1 em]x &= 3&& \\[1 em] \end{aligned} $$
