2. Solve the following inequality.
1.6 Compound InequalitiesA compound inequality consists of inequalities joined with the word AND or the word OR.
You must solve each part separately.
“AND” InequalitiesSo far, you know…
But sometimes we’ll have inequalities with three parts…
Our goal is still the same:
Get the alone on the LEFT!
