We are beginning Mesh analysis in Electric Circuits 1 (Im a graduate from high school with a major in Electronics Engineering, this is college), I remember how to use Simultaneous equations with 2 variables, but I cant seem to remember how to use it with 3 variables.
I have found this page: https://www.themathpage.com/alg/simultaneous-equations-3.htm
But Things dont always go the way as they show it. So do you multiply by the "other number" and add (With 2 variables thats What I do, for example:
3x+5y=2
6x+10y=4
To get rid of x you would multiply the top by 6 and the bottom by -3, and add. Can this be used to get rid of a third variable?)
