Cramer’s Rule 3×3
Posted by Professor Cram in Systems of Equations
Cramer’s Rule (3×3)
For systems of three linear equations in three variables, this Formula Solver program walks you through the steps for finding the solution using Cramer’s Rule (also known as the Third Order Determinant Method). You can even work with your own values!

This really helped for my test! thanks!
Thanks for this explanantion. It really helped me understand the process of Cramer’s Rule.
Could I get that code for this program, I love it.
will be remembered.
thx
Thank you very much!!! very usefull and clear explanation.
sure that final grade will be A+ =)
Thank you so so much! I am reviewing for a placement exam for college and I have to learn this but I NEVER went over this in school and I was like “crap!” because it seems that no where online is there a simple ‘this is how you do it’ kind of explaination. I had managed to decypher most of it from other sites but this made my life so much easier! Its like having a teacher go over an example in class!
Can’t thank you enough!

I needed Cramer’s Rule (3×3) for calculating currents and voltages in network analysis(electronics).
When I searched the web about this guy called Cramer,I couldn`t believe my eyes when I saw that he lived almost 300 years ago.He knew in that period of time more mathematics that I know in these days!
Your explanation was very clear.
Thank you very much!
best math website ever, thanks a lot for the help guys
this is great. thank you very much for this website.
two thumbs up
wow this rocks!
Thanx a lot. Best understood
THANK U JAN I LOVE U SO MUCH
Thank you so much for this explanation! We went over Cramer’s rule in class, and 2×2s are easy enough. When it came to 3×3s everyone else seemed to get it but it just wouldn’t click for me. Even my text book couldn’t explain the process to me. I understand it so clearly now!
Very good explanation. Thank you for the help.
THE BEST WEBSITE EVER U ARE THE BEST
AWESOME PAGE!!! I could not figure out how to do Cramer’s Rule, then I found this site and I actually understand it now!! Thanks!
this really helped me answer my exam…the explanation and the step by step method used in answering a system is well taught…. big thanks!
Thanks a lot, this was really helpful!
thanks a lot this can help me to my 4th quarter exam… Thanks
it helps me so much,thanks for the great program
Thanks so much! I just learned matrices for my test tomorrow! WOOT!!
Thanks for this!!!!! Was able to understand this finally!!!!!
Just keep this website alive!!! It helps us!!! Hehehe!!!
Why do you replace the first column with the answer column???
THANKS for helping me becoming an ENGINEER!!
Thanks a lot,It help me in my Examination.
THANKS for helping me becoming an ENGINEER!!
This was extremely helpful. My Algebra II teacher taught me something really different, and it wasn’t very easy to remember unless I did like 5+ problems everyday. The thing that really got me was the fact that you could do the problem with your own numbers! Arigatou Gozaimasu!
