Question
$$-\frac{\frac{2}{3}}{2}-\frac{2}{3} = 0$$
Answer
This equation has no solution.
Explanation
$$ \begin{aligned} -\frac{\frac{2}{3}}{2}-\frac{2}{3} &= 0&& \text{multiply ALL terms by } \color{blue}{ 6 }. \\[1 em]-6 \cdot \frac{\frac{2}{3}}{2}-6\cdot\frac{2}{3} &= 6\cdot0&& \text{cancel out the denominators} \\[1 em]-2-4 &= 0&& \text{simplify left side} \\[1 em]-6 &= 0&& \\[1 em] \end{aligned} $$
Since the statement $ \color{red}{ -6 = 0 } $ is FALSE, we conclude that the equation has no solution.
