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.
1. 5 - x < 4
2. 4 - 6x > -15 + 1
5 - x < 4
4 - 6x > -15 + 1
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.
