Now that you've studied the many examples for solving inequalities, are you ready for some practice problems?
Let's quickly recap some of the steps for solving these practice problems.
Now you get a chance to solve a few on your own. Try each of the practice problems on your own before checking your answer below. If you get stuck, go back and review the examples problems.
Directions: Solve each inequality and graph the solution. Click here to print out number lines for your practice.
Notice how I had to divide by a negative one in order to make the variable positive. Since I divided by a negative number, I also had to reverse the inequality symbol. This is a very important step that you must not forget!
This problem looked tricky only because I had to first simplify the right hand side. Again, don't forget to reverse your inequality symbol when dividing by a negative number.
It's also good practice to check your answer by substituting a number that fits the solution back into the original inequality. This will verify whether or not your inequality symbol is correct.
So, how did you do? Hopefully you did great, but if not you must check out the extra practice problems in the Algebra Class E-course.

"I'd like to start off by relaying my sincerest gratitude for your dedication in teaching algebra. Your methodology is by far the simplest to follow, primarily because you take the time to include the small steps in between that most other teachers leave out.
It helps to know why you are doing something. I am 45 and heading to college to get my BS in Business. I need to brush up, hence the visit to your site. Great Job!"

"I stumbled onto your site after I found out that I needed to use some fundamental algebra for an assignment. Turns out I had forgotten some things and your great site helped me remember them like "that" (snap of fingers). The organization of the site let me find exactly what I was looking for so easily. Kudos to you for maintaining such a great resource for students of all ages!"

"I just wanted to write and basically thank you for making such a wonderful website! I'm 20 years old and about to take a basic placement test for college. I wanted to brush up on my Algebra skills and I stumbled upon your site. I'm amazed at how simple you make it and how fast I'm remembering Algebra! I don't remember getting most of the answers right when I had an actual teacher in front of me teaching this. Thanks a lot!"

"I am a pensioner living in South Africa. I stumbled on your website, the best thing that could ever happen to me! Your course in Algebra has helped me a lot to better understand the different concepts. Thank you very much for sharing your skills for teaching math to even people like me. Please do not stop, as I am sure that your teachings have helped thousands of people like me all over the world."

This is an amazing program. In one weekend I used it to teach my Grade 9 daughter most of the introductory topics in Linear Relations. I took her up to Rate of Change and now she can do her homework by herself.
