Hlo ........actually ....I am able to get 1 = -1 is it possible ..........well I`m not able to get it`s clear answer on internet.........

How did you get 1=-1?X=-X holds true only for zero and no other real number.If you describe the steps you took to get that, we might be able to help you and show where you went wrong. Cheers.

No its not correct. Every numeric value in mathematics have different values.so this is not possible for anyone to solve this. If it is so then your solution will be incorrect 100%.
