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.
Thank you for this video. In a perfect world you would have been my trigonometry teacher in 1967.
