Question

How do you go about solving when an expression is "sandwiched" between two inequalities, such as -3 < x + 5 < 7?

Answer 1

1<6<8

I think 2<7<9

Answer 2

To simplify it you need to do the same thing to every part of the inequality.
So to get x by itself you need to subtract 5 from every part.

Answer 3

(-3-5) < x < (7-5)

Answer 4
