    So we have |x|>4. This means when do we have distance from x to 0 being greater than 4?

    {x|-4< x< 4} is this it

    Well those numbers give you a distance from 0 less than 4.

    Yes the numbers you stated will always give you a distance from 0 being greater than 4.

    Example 1 |5|>4 but here x>4 since x=5 Another example |-5|>4 but there x<-4 since x=-5 Both of your inequalities you wrote include these numbers and infinitely many more that satisfy the inequalities x<-4 or x>4.
