Using the Combination Method

(Addition Method)

Now that you've studied the Combination Method examples for solving systems of equations, I know you are anxious to practice a few on your own. Ready? Try these two practice problems. Review the examples if you need help, and check your answers using the answer key below. Good luck, I know you can do it.

Quickly review the steps and get started.

- Arrange the equations with like terms in columns.
- Analyze the coefficients of x or y. Multiply one or both equations by an appropriate number to obtain new coefficients that are
**opposites** - Add the equations and solve for the remaining variable.
- Substitute the value into either equation and solve.
- Check the solution.

1. 2x +3y = 5

-x +2y = 8

2. 2x - 3y = 17

3x +2y = 6

With the more difficult concepts in Algebra, the only way to really feel comfortable with the skill, is to practice, practice, practice! The Algebra Class E-courses allow you to not only practice, but it also allows you to check every step of your solution. There's never any question as to where you may have made a mistake! For many, this is the only way to correct your errors and become more proficient with the skill.

Check your answers to the practice problems with the step-by-step solutions below.

Great Job! Now you are ready to move onto solving real world problems!

*"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."*

Noel - South Africa

*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.*
