Examples of absolute value equations and inequalities displayed on a blackboard with a number line illustrating solution intervals.
A blackboard with yellow text "Absolute Value Equations" and four examples of absolute value inequalities, including |x+3| > 4, 4 - 2|2x+1| < 5, |(2/3)x - 1/4| > 5, and |2x + 4| ≤ -8, along with a number line showing intervals from -∞ to 5 and 3 to +∞.
