    Assume 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 .
