Khan Academy: Compound Inequalities

After defining compound inequality problems as "just inequality problems that have more than one set of constraints," Sal goes on to solve several sample problems. Those who have a hard time with multi-step equations might find this...

Practice solving compound inequalities by isolating an unknown variable. This is the second video in a series of four focused on solving compound inequalities.
