Need to solve what are the steps to do so?
1.5<9.1-0.5x<6.8. <they are underlined.
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 .
