Well, first you would have to figure out which values x and y can both have but still be equal. Do you have any in mind yet?
2 to take the place of x, or y?
Yes, if 2 was to take the place of x, it would make sense and be equal to the answer put. If you used 2 for x, It would look like this: (2*2) - 3y = 1 (5*2) + 4y = 14
So that would mean that y would have to be equal to 1.
Do you understand now? :)
2x - 3y = 1 5x + 4y = 14 2x2 - 3 = 1 2x5 + 4 = 14
How are they equal though ? It's 4-3y=1 and 10+4y=14
You are trying to find the values of x and y, correct?
Do x and y both have to be the same in your math problem that was assigned to you?
No I have to find an x and y that make the equations equal
You mean to find x and y values so that they equal the same answer?
Oh, ok. well, what have we found out so far? Do you have an exact answer that they need to end as, or are we just trying to find out one?
Example, did your teacher, or whomever assigned this to you give you an answer that they both must end in? Or are you supposed to figure it out yourselves?
Just find an x and y power in each problem that equal 1 and 14
Ok, well I see that x should probably equal something bigger than 2 to make it a large enough number to be able to equal y.
Ok, so x and y have to both equal 14 as well as 1? in each problem?
Yeah like the first problem equals 1so the x and y need to help it equal one and 14 in the 2nd problem
ok, well, the second problem is 5x + 4 = 14, and we need to find out how to make it equal 1. So, we would have to use a negative number as x then.
X wouod equal 2
ok. but how would that equal to 1? y would have to be a negative number. Maybe y could be -2
That would equal positive 2, and there is no other possible way that we will be able to make it equal 1 unless we use a decimal, and that wouldn't even equal 1 exactly because it would equal somewhere around 1 as a decimal.
Are you sure it asks you to find how to make x and y values to equal both 1 and 14?
Do you know hoe to make those drawings one ere? I'll write it out
How do you do the writing ?
Click, the draw button below this box where you type in a 'comment'. There are 3 blue buttons, click where it says 'Draw'.
this equation is hard i hate my teacher
lol, i meant 2*2 not 2*3 sorry :)
Wait, maybe this answer is correct: 2x - 3y = 1 * 5 = 10x - 15y = 5 you multiply every term in the equation by 5 next you multiply second equation by 2 I'm not sure if that is correct, but that's just another kind of way I was thinking might work. :)
no x equals 2 and y equals 3 we got it ! :)
i meant 1 equals y :)
ya, that's actually what I said in the beginning of the convo lol. Hope I helped though! (Even though, this was a tricky one :)
thanks for your help :)
I became your first fan!
No problem! :)
The sum of two numbers is 17 and their difference is 29. What are the two numbers? do you think we can figure this out ?
Ok, so since the sum of them is a lower number than the difference of them, you would have to be adding a negative number with a positive. Or if that doesn't work, we will try two negatives.
Well, 21 + -4 = 17. So all we have to do is go from there and try to figure out which two numbers will equal 17 when they're added, and 29 when they are subtracted.
i got it 23 and 6 !!
ok so 21 minus -4 = 25. so we will have to lower the first number (21) and greaten the second number (-4).
Sorry lets greaten the first number and the second number. 22 + -5 = 17. 22 minus -5 = 25. Now if greaten both numbers one more time, I think we will have an answer to the problem :) So it would be: 23 + -6 = 17. Now lets see if it will work the other way: 23 minus -6 = 29. And there's your answer.
The two numbers that when added equal 17 and when subtracted equal 29, are 23 and -6.
