Hi tony123;

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

You can substitute this back in (2) and also make (say) x the subject, and hence get an equation in y.
