Question

Verify -(-x)=X for the following​

Answer 1

Step-by-step explanation:

we can write -x as -1*x

therefore -(-x) can be written as -1(-1*x)

                         since -1 * -1 is 1 therefore -(-x)  =  1*x  =  x

substituting -(-x) for x in the main question, we get x=x which is               always true

Answer 2

-(-x) can be written as -1(-1x

 now, -1 * -1 is 1 therefore -(-x)  =  1x  =  x

substituting -(-x) for x in the main question, we get x=x which is   verified by LHS and RHS
