Question

Verify the following for x = -(-x) x =-7/9​

Answer 1

Answer:

it true... ...........................

Answer 2

Answer:

x= -(-x) (Given)

ATQ

x= -7/9

( We have to verify whether X = -(-x) or not if X = -7/9)

So,

x= -(-x) (LHS) = -7/9 ( RHS)

=-(-×(-7/9)

=[-×-] × [-7/9]

=[+] × (-7/9)

=-7/9

L.H.S = R.H.S

-7/9 = -7/9

Hence, verified
