Best ResponseYou've already chosen the best response.0I have tried to work it out myself and this is what I got. 5x+y(7x13)=17 So I going with x=35/7 which gave me 5 so that is my x but I can get my y= yet. I tried and gt 22/20 thats not right?????

Best ResponseYou've already chosen the best response.0Your process seemed right, but I got x to be 5/2

Best ResponseYou've already chosen the best response.0Also realize there is no y once you substitute it into that one equation, I think you just had a typo though.

Best ResponseYou've already chosen the best response.0the 22/20 is what I got

Best ResponseYou've already chosen the best response.0For y I got 9/2. Now you can check these numbers if you plug them into one of the equations and both sides are equal.

Best ResponseYou've already chosen the best response.0So can you help me with it again

Best ResponseYou've already chosen the best response.0Yes. So it looks like you tried to solve the first equation for y to get y=7x13 Then it looked like you plugged it into the 2nd equation and should have gotten 5x+(7x13)=17

Best ResponseYou've already chosen the best response.0All you need to do next is solve for x, plug it back into one of the equations and solve for y.

Best ResponseYou've already chosen the best response.0so when I do that then I get 13y+17/7y+5 and the whole problem is negative with a neg.sign front understand

Best ResponseYou've already chosen the best response.0I don't quite see what you are doing...5x7x13=17 then 12x=30 then x=5/2 so plug 5/2 into either of the equations to get y. So for example, 5(5/2)+y=17 then (25/2)+y=17 and y=9/2

Best ResponseYou've already chosen the best response.0ok so what is the order pair

Best ResponseYou've already chosen the best response.0can you please give me the order pair to this question

Best ResponseYou've already chosen the best response.0(x,y) so (5/2,9/2) which is the same as (2.5,4.5)

Best ResponseYou've already chosen the best response.0so that is the order pair?

anonymous

Best ResponseYou've already chosen the best response.0Yes. If you plug in both the x and y into either of those equations you should get the left side equal to the right.

Best ResponseYou've already chosen the best response.0thanks again, is there a program that helps you work these out and learn them

anonymous

Best ResponseYou've already chosen the best response.0so I need to put (2.5,4.5) in or (5/2, 9/2) in

Best ResponseYou've already chosen the best response.0when I put in the first one it said incorrect!!!

Best ResponseYou've already chosen the best response.0The answers are correct based on the equations you gave me. I promise.

Best ResponseYou've already chosen the best response.0sorry the top one is suppose to be 4y sorry so 7x+4y=13 and 5x+y=17 I am so sorry I could not figure out what I was doing wrong

Best ResponseYou've already chosen the best response.0http://www.webmath.com/solver2.html here is something I found that does solve systems of equations, well at least 2 of them. I looked over their work, and it seems like it can be confusing. I would recommend trying to do them on your own solving for x or y like we did, and maybe using that website to check steps if you made a mistake. There's probably something better out there somewhere.

Best ResponseYou've already chosen the best response.0So can I get the order pair for this then please and I can move on to the next.....please...
