Re: Systems Of Linear EquationsHi MERTICH; Now substituting any value into x will yield a solution to the system. 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. #4 20131202 17:13:05
Re: Systems Of Linear Equations
I have edited the system. the other z is positive. Sorry guys. Last edited by MERTICH (20131202 17:14:25) #5 20131202 17:16:30
Re: Systems Of Linear Equations
I am so sorry Bobbym . The other z is positive. #6 20131202 18:14:54
Re: Systems Of Linear EquationsHi; Substituting for y will all solutions, but unfortunately this post is too small to contain them. In mathematics, you don't understand things.

Re: Systems Of Linear Equationshi MERTICH You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #8 20131202 20:03:20
Re: Systems Of Linear EquationsThank you guys, I thought as much, but you know, when doing it alone you doubt yourself. I have learnt something today : a system with three variables and two equations will NOT yield precise values for the variables, except by inserting the infinite number of all possible solutions. Thanx. Will be back soon. #9 20131202 21:56:27
