Find a solution to the system of simultaneous equations
In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.
Here's how I'd tackle this.
This quadratic has two solutions
You can substitute this back in (2) and also make (say) x the subject, and hence get an equation in y.
