Answer
$$ x = -4 $$
Explanation
$$ \begin{aligned} 2(x+6) &= x+8&& \text{simplify left side} \\[1 em]2x+12 &= x+8&& \text{move the $ \color{blue}{ x } $ to the left side and $ \color{blue}{ 12 }$ to the right} \\[1 em]2x-x &= 8-12&& \text{simplify left and right hand side} \\[1 em]x &= -4&& \\[1 em]x &= -4&& \\[1 em] \end{aligned} $$
