Answer:

No answer. Just refer to the explanation. ;)

Step-by-step explanation:

To prove:

$\dfrac{5}{11} + \left( - \dfrac{7}{9} \right) = - \dfrac{7}{9} + \dfrac{5}{11}$

Taking LHS,

$\dfrac{5}{11} + \left( - \dfrac{7}{9} \right)\\\\\\= \dfrac{5}{11} - \dfrac{7}{9}\\\\\\= \dfrac{45 - 77}{99}\\\\\\= - \dfrac{32}{99}$

Now, taking RHS,

$- \dfrac{7}{9} + \dfrac{5}{11}\\\\\\= \dfrac{-77 + 45}{99}\\\\\\= - \dfrac{32}{99}$

Since LHS = RHS,

$\dfrac{5}{11} + \left( - \dfrac{7}{9} \right) = - \dfrac{7}{9} + \dfrac{5}{11}$

Hence Proved.
