The answer varies depending on what form you want your answer in like fraction, decimal, etc. So we have the expression -x. And if x = -100/33 then we can substitute this value in the expression for x. So it would be
-(-100/33) and we can simplify it since and - and - is + so the final answer in fraction form would be 100/33. If you want to convert it into a decimal you simply divide 100 by 33 and would get 3.03 with the 03 repeating so you would but a dash over the 03 to indicate that it is repeating continuously. I hope you find this helpful.
