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!

break up the inequality, and solve them like you would with algebraic equations with "x"s on both sides of the equation.

solve for

s_1=x+1<2x+7

and

s_2=2x+7<x+5

your solution should display

s_1<x<s_2

OR

subtract x from all terms, then you would have something your more familiar with

1<x+7<5
