Question

verify that -(-x)=x for x= -13/7

Answer 1

hiii!!!

here's ur answer..

we have to verify - ( - x ) = x

given x = -13/7

LHS :-

==> - ( - x )

= - [ - ( - 13/7 ) ]

= - ( 13/7 )

= - 13/7

RHS :-

==> x

= - 13/7

hence, it's proved that LHS = RHS

hope this helps..!!

Answer 2

Given: $x = \frac{-13}{7}$

To verify:  $-(-x) = x$

Solution: Given that, $x = \frac{-13}{7}$

We need to verify thet $-(-x) = x$

Taking L.H.S.

⇒  $- [ - (\frac{-13}{7})]$

⇒ $-[\frac{13}{7}]$ = $\frac{-13}{7} = x$ = R.H.S.

Hence, verified that $-(-x) = x$.
