Question
$$-\frac{2}{3}-\frac{7}{8} = 0$$
Answer
This equation has no solution.
Explanation
$$ \begin{aligned} -\frac{2}{3}-\frac{7}{8} &= 0&& \text{multiply ALL terms by } \color{blue}{ 24 }. \\[1 em]-24\cdot\frac{2}{3}-24\cdot\frac{7}{8} &= 24\cdot0&& \text{cancel out the denominators} \\[1 em]-16-21 &= 0&& \text{simplify left side} \\[1 em]-37 &= 0&& \\[1 em] \end{aligned} $$
Since the statement $ \color{red}{ -37 = 0 } $ is FALSE, we conclude that the equation has no solution.
