Question

3. Verify [-(-x)] = x for the following values:


(b) x = -6/7

​

Answer 1

Answer: 6/7

• Explanation: = [-(-6/7)]

= +6/7

= 6/7

Answer 2

Answer:

Step-by-step explanation:

x = -6/7

L.H.S                                R.H.S

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

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

=> [-( +6/7 )]                    = -6/7

=> -6/7                           = -6/7

Therefore, L.H.S = R.H.S....

Hope it helps !!!
