Answer
$$ x = 7 $$
Explanation
$$ \begin{aligned} 2(x+4) &= 3x+1&& \text{simplify left side} \\[1 em]2x+8 &= 3x+1&& \text{move the $ \color{blue}{ 3x } $ to the left side and $ \color{blue}{ 8 }$ to the right} \\[1 em]2x-3x &= 1-8&& \text{simplify left and right hand side} \\[1 em]-x &= -7&& \text{switch signs on both sides} \\[1 em]x &= 7&& \\[1 em] \end{aligned} $$
