Ian R. PorteousDon't know if your aware but Ian R. Porteous passed away reciently and there is a new article about him. You might want to have a look at the article.--Salix (talk): 01:16, 5 March 2011 (UTC)[reply]
TalkbackHello, Fly by Night. You have new messages at Bgwhite's talk page.

You can remove this notice at any time by removing the {{Talkback}} or {{Tb}} template.[reply] clopen for businessI'm the IP who has been asking you questions at clopen sets, and I wanted to let you know, I'm curious to hear your next response on that talk page. 64.202.138.67 (talk) 14:38, 14 March 2011 (UTC)[reply] I agree that the discussion on http://en.wikipedia.org/wiki/Wikipedia:Reference_desk/Mathematics#Simultaneous_equation should not take place. Did you consider it helpful to the OP in the first place to grumble over my answer? Bo Jacoby (talk) 12:51, 27 March 2011 (UTC).[reply]
See for example [[1]]. The solution to x^5+x^4-3=0 is written 1.09404. If you request exact form you get x = [root of x^5+x^4-3 near x = 1.09404]. So you get the equation and the approximation, and that's all. I did the same thing: expressed the equation and the approximate solution. The use of numerical fractions and infinite decimal fractions are less general and outdated. See also numerical analysis and algebraic equation. I wanted to provide to the unknown OP the modern approach. Your know-it-all attitude is in my opinion not improving my answer. Bo Jacoby (talk) 21:21, 27 March 2011 (UTC).[reply]
Can't you provide a more precise reference to support your point of view than "another mathematician (or a school boy on a bus)"? I answered OP's question in a general way, not using the fact that the equations are linear. Writing the solution as x=-135/53 is no progress from the equation 53x+135=0. The approximation x=-2.55 is progress. I provided both the equation and the approximation, which is the proper thing to do, as shown by the wolframalpha example. You are the one who went on the attack by adressing me rather than adressing the OP. You were (and are) being rude and undiplomatic. Bo Jacoby (talk) 06:58, 28 March 2011 (UTC).[reply] You really need to stop now, the discussion has ceased to be productive. --Salix (talk): 08:02, 28 March 2011 (UTC)[reply]
