Step-by-Step Solution:
Step 1 of 3

Math 121 Chapter 2 Notes Lesson 2.2 – Linear Inequalities in One Variable Example 1. 3x – 4 ≥9 + 5x (Add 4 and subtract 5x from both sides.) -2x ≥ 13 (Divide both sides by -2 and flip the sign.) x ≤ -6.5 Interval notation: (-∞, -6.5] (On a number line, a solid mark would be on -6.5 and point toward negative infinite.) Example 2. -24 < 3x – 3 ≤ 18 (Add 3 to all sides of the equation and divide by 4 to isolate the x in the middle.) -7 < x ≤ 7 (On a number line, this would look like an
