Answer 1

Step-by-step explanation:

Let us first consider the LHS

$\frac{-2}{3}-\frac{9}{20} \\\\= \frac{-40-27}{60}\\\\= \frac{-67}{60}$

Now lets consider RHS

$\frac{9}{20}-\frac{-2}{3}\\ \\= \frac{9}{20}+\frac{2}{3} \\\\= \frac{27+40}{60} \\\\= \frac{67}{60}$

From LHS and RHS

It is evident that LHS is not equal to RHS..

Hence Proved...
