Question

verify the following.​

Answer 1

LHS =

$- 20 + ( \frac{3}{ - 5} + \frac{ - 7}{ - 10} ) \\ = - 20 + ( \frac{6 - 7}{ - 10} ) \\ = - 20 + \frac{1}{10} \\ = \frac{199}{10}$

RHS =

$( - 20 + \frac{3}{ - 5} ) + \frac{ - 7}{ - 10} \\ = (\frac{100 + 3}{ - 5} ) + \frac{7}{10} \\ = \frac{ - 206 + 7}{10} \\ = \frac{199}{10}$

Hence,

LHS = RHS
