Systems of simultaneous equations are intriguing.
They are used to identify points that the equations have in common (in this case, an x and a y value). Interestingly, there are a number of ways to solve equations simultaneously. The two primary methods that are first learned in middle high school are substitution and elimination. In time, mathematics students also learn about the use of determinants and matrices as well (not to mention vectors, etc.).
My plan (at this stage) is to address these four key methods/topics on this website.
Brilliant!!! This helps so much!!! So much easier than anything else I have found. This is now simple.
Thanks again for showing the simple way of doing this. I look forward to the next video!! Absolutely brilliant.
Once again, excellent! I’ve watched many others, that have not helped nearly as much as these. Thanks for making it so easy to understand. When things get complicated, it is easy to make a mistake, but your method of writing down the structure helps to prevent mistakes.
Thanks a million!!! I’ve watched many videos and read tutorials, but still could not get two in a row correct on Khan Academy. Your explanation was so clear and simple that it finally made sense to me and now I can get all of the problems correct!!! Thank you very much.
It all makes total sense now! Thanks very much for all the derivative videos!!! Very helpful.
