Question

3. Verify [-(-x)] = x for the following value x=-6/7​

Answer 1

Step-by-step explanation:

=x=-6/7 [-(-x)]

=[-(+6/7)]

=(-6/7)

=-6/7

=L.H.S=R.H.S

Hence , Verified

Answer 2

Answer:

Step-by-step explanation:

x = -6/7 (given)

To verify --> [-(-x)] = x

Verification --> [-(-{-6/7})] = -6/7

=> (-{-6/7}) = -6/7           (Minus and minus combine to become plus)

=> -6/7 = -6/7

∴ It is verified as LHS = RHS.

EXTRA:

FYI this equation is valid for all values of x.

Explanation:

[-(-x)] = x

=> [x] = x         (Minus and minus combine to become plus)

=> x = x

So, this equation is valid for all values of x because LHS = RHS.
