Answer 1

$\frac{1}{x}>1, \\x \neq 0, \\ \frac{1}{x}-1>0, \\ \frac{1-x}{x}>0, \\ \left [ {{ \left \{ {{1-x<0,} \atop {x<0;}} \right. } \atop { \left \{ {{1-x>0,} \atop {x>0;}} \right. }} \right. \left [ {{ \left \{ {{x>1,} \atop {x<0;}} \right. } \atop { \left \{ {{x<1} \atop {x>0;}} \right. }} \right. \left [ {{x\in\varnothing,} \atop {0<x<1;}} \right. \\ 0<x<1.$

$\frac{x-1}{x} <1, \\ x \neq 0, \\ \frac{x-1}{x}-1<0, \\ -\frac{1}{x} <0, \\ \frac{1}{x} >0, \\ x>0.$
