Solving Systems of Linear Inequalities
One thing that puzzles a lot of young algebrists is the factors in a word problem that are taken as "understood". This presentation on solving systems of linear inequalities does a great job walking the learner through how to tease those...

Solve Simultaneous Linear Inequalities by Graphing
It would be an inequality if you stopped at linear equations and didn't graph linear inequalities too. The last video in the series combines the idea of compound inequalities with linear systems to create a new type of system. Learners...
