Sorry, the calculator cannot solve such ualities (nothing to do with the absolute function).To find the solution set you need to study the two cases for the absolute value.Case 1If x-1> 0, the absolute value is x-1. The inequality takes the form x-1<9. You can solve it as x<10Case 2 If x-1<0, then the absolute value is 1-x. The inequality becomes 1-x<9. The solution for this inequality is x>-8Combine the two domains to find the intersection-8<x<10
