Solving algebra equations with variables on both sides is really tough. But, you will have no problems solving these equations after you follow the step-by-step instructions in these 3 examples.
This is it! Our last type of equation to solve before applying our knowledge to solve real world problems! Yes... the whole reason we are learning to solve these equations!
So far, you've learned how to solve one-step equations, two-step equations, and equations with fractions. If you haven't mastered these skills or need a refresher, please go back and review these lessons before attempting this one! It will be so much easier if you have the background!
So, if you are ready, let's move on!
Solving algebra equations with variables on both sides look intimidating, but they really aren't that hard if you have the background skills. In fact, I think these types of equations are fun because it's like moving pieces of a puzzle around.
This is what you need to remember:
Let's look at a few examples.
This next example shows how to solve if the distributive property is involved.
Yes, this is a confusing topic, so if you are still having trouble, check out example 2 on video.

This last example shows how to solve if fractions are involved.
Example 3 on video...
It doesn't look too hard, does it? Remember: it's like moving puzzle pieces around - all the variable terms on one side and all the constant terms on the other side!
Variables on Both Sides: 4p +40 = 26p
Variables on Both Sides (with Fractions): 3/7w - 11 = -4/7w
Variables on Both Sides (and the distributive property): -11-5a = 6(5a+4)
Variables on Both Sides: 2c+6 = 1-3c
Another Variables on Both Sides: 4x - 5 = 12x -69

I am a homeschool mom of five who struggled with finding a solid algebra program for my older boys until I came upon your algebra class. Your tutorials are straight forward and detailed. Your assignments are designed in such a way that we can spend extra time on what my children need to and move on when they understand something more easily.
I am a math-lover myself and am excited that you have finished part 2 of this course. My boys are understanding algebra in a way that they never were able to with other courses due to the detail and care that are in each of your lessons. I also appreciate that you are available to answer questions.
Finding your site was such a blessing to me! I have been out of school for 13+ years and finding out that my next course would be Algebra scared me to death!
I have now found a new love of learning for algebra--something I never thought would happen. After indulging in the section of functions, I decided to explore other areas that I have just learned. It made areas such as inequalities and graphing so much easier to grasp!
I just wanted to thank you for your passion and dedication for helping others! I also love the fact that you add in some humor, too. I have shared your site with classmates and hope they take an opportunity to look into it as well! Thank you----
With greatest respect,
I just spent 3 hours doing Unit 5 Lessons 1 & 2 because that is what I am learning at school this week, and cannot believe my progress. I so wish I would have found your course sooner. It is amazing. You explain everything in such clarity it's like night and day. Thank you so much for getting me started. I am so happy you can't believe it. You are the best instructor ever!
