Divide out the factors to clear the denominators:

For additional explanation on fractional equations, please see my own website. You can find my website by doing a Google search for my name "Dr. Robert J. Rapalje". Look for "Rapalje Homepage", which should be the first item on the search. Once you find my homepage, for a written explanation, click on "Basic, Intermediate, and College Algebra: One Step at a Time." Look in Intermediate Algebra in Chapter 2 for Section 2.07 Fractional Equations. There you will find a detailed explanation, and solutions to problems in LIVING COLOR!!

In addition, there is a FREE video of me teaching this topic a few years ago. To see the video, from my Homepage, look for "Rapalje Videos in Living Color." Choose Intermediate Algebra, and look for the video called "Fractional and Literal Equations."

I have many other topics explained in this way from Basic, Intermediate, and College Algebra. Please check out my website to see what I have. It's all FREE.
