Question
$$16-\frac{12}{2} = 2$$
Answer
This equation has no solution.
Explanation
$$ \begin{aligned} 16-\frac{12}{2} &= 2&& \text{multiply ALL terms by } \color{blue}{ 2 }. \\[1 em]2\cdot16-2\cdot\frac{12}{2} &= 2\cdot2&& \text{cancel out the denominators} \\[1 em]32-12 &= 4&& \text{simplify left side} \\[1 em]20 &= 4&& \\[1 em] \end{aligned} $$
Since the statement $ \color{red}{ 20 = 4 } $ is FALSE, we conclude that the equation has no solution.
