Solution
\[\text{We have to verify that} x \times y = y \times x . \]
\[ x = \frac{- 3}{5}, y = \frac{- 11}{13}\]
\[x \times y = \frac{- 3}{5} \times \frac{- 11}{13} = \frac{33}{65}\]
\[y \times x = \frac{- 11}{13} \times \frac{- 3}{5} = \frac{33}{65}\]
\[ \therefore \frac{- 3}{5} \times \frac{- 11}{13} = \frac{- 11}{13} \times \frac{- 3}{5} \]
\[\text{Hence verified .} \]
