Question
$$3x-2(x+4) = x+8$$
Answer
This equation has no solution.
Explanation
$$ \begin{aligned} 3x-2(x+4) &= x+8&& \text{simplify left side} \\[1 em]3x-(2x+8) &= x+8&& \\[1 em]3x-2x-8 &= x+8&& \\[1 em]x-8 &= x+8&& \text{move the $ \color{blue}{ x } $ to the left side and $ \color{blue}{ -8 }$ to the right} \\[1 em]x-x &= 8+8&& \text{simplify left and right hand side} \\[1 em]x-x &= 16&& \\[1 em]0 &= 16&& \\[1 em] \end{aligned} $$
Since the statement $ \color{red}{ 0 = 16 } $ is FALSE, we conclude that the equation has no solution.
