I know fractions are difficult, but with these easy step-by step instructions you'll be solving equations with fractions in no time.
Do you start to get nervous when you see fractions? Do you have to stop and review all the rules for adding, subtracting, multiplying and dividing fractions?
If so, you are just like almost every other math student out there! But... I am going to make your life so much easier when it comes to solving equations with fractions!
Our first step when solving these equations is to get rid of the fractions because they are not easy to work with!
Let see what happens with a typical two-step equation with the distributive property.
In this problem, we would typically distribute the 3/4 throughout the parenthesis and then solve. Let's see what happens:
Yuck! That just made this problem worse! Now we have two fractions to contend with and that means subtracting fractions and multiplying fractions.
So... let's stop here and say
We are going to learn how to get rid of the fractions and make this much more simple!
So... what do we do? We are going to get rid of just the denominator in the fraction, so we will be left with the numerator, or just an integer!I know, easier said than done! It's really not hard, but before I get into it, I want to go over one algebra definition.
We need to discuss the word term.
In Algebra, each term within an equation is separated by a plus (+) sign, minus (-) sign or an equals sign (=). Variable or quantities that are multiplied or divided are considered the same term.
That last example is the most important to remember. If a quantity is in parenthesis, it it considered one term!
Let's look at a few examples of how to solve these crazy looking problems!
Hopefully you were able to follow that example. I know it's tough, but if you can get rid of the fraction, it will make these problems so much easier. Keep going, you'll get the hang of it!

Yes, the equations are getting harder, but if you take it step-by-step, you will arrive at the correct solution. Keep at it - I know you'll get it!

"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.
