THE INEQUALITY SYMBOL NOW CHANGES

3. The inequality symbol now changes:Solving Compound InequalitiesA compound inequality is a combination of two inequalities. For example, take the compound inequality–3 x+ 1 4. To solve this, subtract 1 from all parts of the inequality. –3 – 1 x + 1 – 1 4 – 1. Simplify.–4 x3. Therefore, the solution set is all numbers between –4 and 3, not including –4 and 3.
