Question

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

Answer 1

You can add or subtract from all three parts and preserve the inequality sign. In this case, subtract 5 from each of the 3 parts.

Answer 2

you need separate it in two parts

x+5>-3 and
x+5<7

x+5>-3
x>-8

x+5<7
x<2

x has an interval of (-8,2)

hope so much that is understandably

good luck
