Question
$$\frac{20}{10}\cdot10+5-5 = 0$$
Answer
This equation has no solution.
Explanation
$$ \begin{aligned} \frac{20}{10}\cdot10+5-5 &= 0&& \text{multiply ALL terms by } \color{blue}{ 10 }. \\[1 em]10 \cdot \frac{20}{10}\cdot10+10\cdot5-10\cdot5 &= 10\cdot0&& \text{cancel out the denominators} \\[1 em]200+50-50 &= 0&& \text{simplify left side} \\[1 em]200+50-50 &= 0&& \\[1 em]200 &= 0&& \\[1 em] \end{aligned} $$
Since the statement $ \color{red}{ 200 = 0 } $ is FALSE, we conclude that the equation has no solution.
