Hello people. How do you guys do math systems/substitution so easily? I just never seem to be able to solve a question without going wrong a couple of times times. Please do not tell me to take extra classes. They are costly and I cannot afford them. Any other suggestion would be more than welcome.
You can find numerous links on the internet if you search the keyword math systems/substitution. Most of the content is however designed for the people who already have some knowledge about this subject. If you are a complete novice, you should use Algebra Buster. Is it easy to understand and very helpful too.
Thanks for the detailed information, this seems great. I wanted something exactly like Algebra Buster, because I don't want a program which only solves the exercise and gives the final result, I want something that can actually show me how the exercise has to be solved. That way I can learn it and after that solve it on my own, not just copy the results. Where can I find the program?
