**drwls**, Sunday, February 10, 2013 at 1:00pmAssume the > signs are really ¡Ý

We will change them later.

Subtract 9.1 from each term in the inequality

-7.6 < -0.5x < -2.3

Double each term

-15.2 < -x < -4.6

Multiply each term by -1, changing the directions of the < signs,

4.6 > x > 15.2

4.6 ¡Ý x ¡Ý 15.2

Let the > signs be underlined, ¡Ý .
