Could you please explain the Cramer's Law to me?
It's shortest method, the concept behind it, why we use it and where we apply it?
thanks in advance,

The Anarchist is back! Where've you been? Good to hear from you again.

Cramer's law (rule) is a method for solving simultaneous linear equations using determinants of matrixes. It is often the shortest method to use when you have 3 or more simultaneous equations to solve. Assuming you know how to calculate determinants, this site shows an example of the cookbook method used: www.mathonline.org/mho/view.cgi?11944

Just wanted to echo Gerry. Welcome back and I hope you stick around.

Gee.....
Can't put in words how great it feels to be remembered.
And,oh,Gerry you also recalled my anarchist nick; which I hadn't inserted in my hurried post!

Well, thnx for the prompt reply [and thnx too for giving me such a warm welcome back].

I knew I could always depend on my ol' friend AnswerPool to help me out ASAP
Pin~Jinx/ anarchist for sure

[P.S.] The reply to 'where have I been' etc are rather long, and I don't want to mess with the administrators by being guilty of threading. Although Karrow knows my personal email addresses, and part of my personal life too.
