How do you solve three equations in three unknowns?Equation 1 has p1 and p3 in. #2 20121128 06:38:44
Re: How do you solve three equations in three unknowns?What are the equations? 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. #3 20121128 06:41:53
Re: How do you solve three equations in three unknowns?Will it be easier if I right in neat on paper and then upload picture for you bobby? Or easier for you if I write on here in the (messy) way? #4 20121128 06:46:57
Re: How do you solve three equations in three unknowns?Hi; 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.

Re: How do you solve three equations in three unknowns?(4  P3) /2 = P1 #6 20121128 07:04:10
Re: How do you solve three equations in three unknowns?Hi; Is the the system you want solved? P1 =  ( 1 / 2 ) P2 = 1 / 2 P3 = 5 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. #7 20121128 08:40:44
Re: How do you solve three equations in three unknowns?Oh my god?! How did you do that? This is incredible. Apologies for the delayed response, internet went down for over an hour. #8 20121128 08:43:04

Re: How do you solve three equations in three unknowns?
I think so, that's what I tried but I always got it wrong! #10 20121128 09:03:10
Re: How do you solve three equations in three unknowns?Did you use equation 1 and substitute for P1 into equation 3? 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. #11 20121128 13:58:12
Re: How do you solve three equations in three unknowns?
I tried substituting everything into everything, I keep going round in circles and have two unknowns in every equation. But this can be done apparantly it shouldn't be too difficult. I just cannot see it. #12 20121128 14:08:23
Re: How do you solve three equations in three unknowns?Hi; You substitute for P1 in equation 3. That gives 2 equations with 2 unknowns. Can you solve now? 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. #13 20121128 14:09:34
Re: How do you solve three equations in three unknowns?Wait I think I just did it, i got p1 = 1/2. We cannot have a negative price so I won't solve for p2 and p3 yet, I must have done something wrong earlier. This is awful I will not be asleep for a while. #14 20121128 14:11:06
Re: How do you solve three equations in three unknowns?P1 = (  1 / 2 ). If that does not fit then you have set the problem up wrong. 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. #15 20121128 14:16:00
Re: How do you solve three equations in three unknowns?THANK you for guiding me on this. Please don't waste your time here, I will go over this freshly again and see what I have done wrong. I HAVE to get to a stage with three equations in three unknowns, it just means my numbers were wrong earlier because a negative price cannot happen in this particular question, but thanks to you at least i can solve three equations in three unknowns! #16 20121128 14:20:19
Re: How do you solve three equations in three unknowns?Hi;
Math is hard work for everybody. Go over how you set the problem up there is certainly a mistake there. 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. #17 20121129 05:42:37
Re: How do you solve three equations in three unknowns?DONE IT!!! #18 20121129 06:36:02
Re: How do you solve three equations in three unknowns?Your work looks like you are doing some kind of physics. You have my sympathy... 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. #19 20121129 07:03:51
Re: How do you solve three equations in three unknowns?I am doing a bit of EVERYTHING! #20 20121129 07:12:36
Re: How do you solve three equations in three unknowns?Unfortunately at one time I loved physics and group theory. I actually thought I was doing mathematics... Then like Saul, I was struck by lightning and saw the light. Computational mathematics! 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. #21 20121129 07:25:13
Re: How do you solve three equations in three unknowns?
Hahahaha! That is brilliant!
