Question 564091: Hi!
I need help on an inequality involving absolute value. The problem is |(1/x)-3|>6. I broke the inequality into 2 equations, (1/x)-3>6 and (1/x)-3<-6. I then proceeded to get the equations, (1/x)>9 and (1/x)<-3. I am stuck from here. The answer I should get is (-(1/3),0) union (0,(1/9)). Thank you for any help you can give me.
