Best ResponseYou've already chosen the best response.0\[x+2=\frac{1}{x}\times (x)\]

Best ResponseYou've already chosen the best response.0\[x=(x)(\frac{1}{x})+2\]You have it backwards, I believe, satellite.

Best ResponseYou've already chosen the best response.0would the interval be \[2<x \le0\]?

Best ResponseYou've already chosen the best response.0\[x=1+2=1\]1 is two more than 1*(1/1).

Best ResponseYou've already chosen the best response.0oh, if satellite had it backwards that would make sense. The interval would have to be \[0<x \le2\]

Best ResponseYou've already chosen the best response.0The number lies in an infinite number of different intervals. \[1290 \le x \le 2\]\[0.99999 \le x \le 4\]The question isn't specific to what interval it wants. Your answer works, though.
