The solution is x(0,12)(12,0)

Explanation:

graph{(y-|1/x|)(y-2)=0 [-10, 10, -5, 5]}

x0

For absolute values, there are 2 solutions.

1x>2

, 1x2>0

12xx>0

BY a sign chart the solution is S1=x(0,12)

and

1x<2

, 1x+2>0

1+2xx>0

BY a sign chart the solution is S2=x(12,0)

The solution is

S=S1S2
