Question

question is verify that.... ​

Answer 1

Step-by-step explanation:

Solution:-

$\implies{ \blue{ - 20 + ( \frac{3}{ - 5} + \frac{ - 7}{ - 10}) = ( - 20 + \frac{3}{ - 5} ) + \frac{ - 7}{ - 10} }}$

remove the bracket from both side

$\implies - 20 + \frac{3}{ - 5} + \frac{ - 7}{ - 10} = - 20 + \frac{3}{ - 5} + \frac{ - 7}{ - 10} \\ \implies - 20 + \frac{ - 3}{5} + \frac{7}{10} = - 20 + \frac{ - 3}{5} + \frac{7}{10}$

now find 7/10 and -3/5 into rhs and -20 in lhs

$- 20 + 20 = \frac{ - 3}{5} + \frac{3}{5} + \frac{7}{10} - \frac{7}{10}$

$\implies{ \boxed{ \red{0 = 0}}}$

LHS=RHS
