3x2y=1 how to find the value of x and y?HI, #2 20130201 22:29:44
Re: 3x2y=1 how to find the value of x and y?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. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #4 20130201 22:33:06
Re: 3x2y=1 how to find the value of x and y?I do not understand, aren't you solving a simultaneous set of linear equations? What has that to do with set theory? Is that h a variable? 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. #5 20130201 22:33:28
Re: 3x2y=1 how to find the value of x and y?quiz is this . find x and y if (3x+y, x1) = (x+3, 2y2x) #6 20130201 22:36:45
Re: 3x2y=1 how to find the value of x and y?this question is from ordered pairs, so that first i have to find x and y #7 20130201 22:38:44
Re: 3x2y=1 how to find the value of x and y?I am getting x = 1 and y = 1. 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. #8 20130201 22:41:45
Re: 3x2y=1 how to find the value of x and y?yes, perfect, is there any method or something else to find value of x and y? #9 20130201 22:45:23
Re: 3x2y=1 how to find the value of x and y?There are several methods: Do you know how to solve that? 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 20130201 22:58:23
Re: 3x2y=1 how to find the value of x and y?Clean this one up a bit by subtracting x from both sides. Clean up the second one Add 2x to both sides Subtract 2y from both sides. Add one to both sides We now have Did you follow up to here? 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. #12 20130201 23:05:58
Re: 3x2y=1 how to find the value of x and y?how do you think what to add or not? #13 20130201 23:10:34
Re: 3x2y=1 how to find the value of x and y?ya i got it till here, but what next to find x and y? #14 20130201 23:17:53
Re: 3x2y=1 how to find the value of x and y?
Just trying to get it into the form of all the variables on the left and all the numbers on the right so we can make the next bunch of moves. 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 20130201 23:26:23
Re: 3x2y=1 how to find the value of x and y?ok, but what will be the next step to find x value? #16 20130201 23:32:45
Re: 3x2y=1 how to find the value of x and y?We would like to subtract or add the bottom equation from the top one and make one variable disappear. But when I do that 2x  3x = x, that did not disappear and y + (2y) = y so no luck there either. If I multiply the top equation by 3 I get Now if I multiply the second equation by 2 I get So I have changed the equations again to 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. #18 20130201 23:45:43
Re: 3x2y=1 how to find the value of x and y?Can you finish now or do you want me to do more? In mathematics, you don't understand things. You just get used to them.
