Answer 2

$\huge{\underline{\tt{QUESTION:-}}}$

Verify that -(-x) = x for :-

(a) 11/15

(b) -21/37

$\huge{\underline{\tt{ANSWER:-}}}$

(a) 11/15

$\bold{\underline{\underline{\pink{Sol.-}}}}$ L.H.S. -

-(-11/15)

= +11/15

= 11/15 = R.H.S.

$\bold{\blue{\underline{\green{L.H.S. \: = \: R.H.S.}}}}$

Hence, verified !

(b) -21/37

$\bold{\underline{\underline{\pink{Sol.-}}}}$ L.H.S. -

-[-(-21/37)]

= -[21/37]

= -21/37 = R.H.S.

$\bold{\blue{\underline{\green{L.H.S. \: = \: R.H.S.}}}}$

Hence, verified !
