Step-by-step explanation:

- x - = +

according to this -(-x) = x is true.

but if values are taken, lets check whether it is true or not...

1.  If x= 4/5

-(-4/5) = 4/5      - x - = +            4/5 = 4/5

2. If x= 2/5

-(-2/5) = 2/5      - x - = +            2/5 = 2/5

so, we have found that - x - = +.. through this v have verified the question
