    Advanced Function Inequalities
    There is one type of question regarding inequalities that I cannot get. I can get most of the other ones but when you need to solve for a question with an x on all 3 sides of the inequaltiy. An example of this type of question would be:

    x+1<2x+7<x+5

    Thanks for any help!
