Re: Find a solution

Hi tony123;


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

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