Question
$$3x-12 = 3x+1$$
Answer
This equation has no solution.
Explanation
$$ \begin{aligned} 3x-12 &= 3x+1&& \text{move the $ \color{blue}{ 3x } $ to the left side and $ \color{blue}{ -12 }$ to the right} \\[1 em]3x-3x &= 1+12&& \text{simplify left and right hand side} \\[1 em]3x-3x &= 13&& \\[1 em]0 &= 13&& \\[1 em] \end{aligned} $$
Since the statement $ \color{red}{ 0 = 13 } $ is FALSE, we conclude that the equation has no solution.
