What is the solution for this system of linear equations? I'm stuck,
y=2x+1
y+7x17
so 2x+1=7x17
??

Best ResponseYou've already chosen the best response.1add \(2x\) to both sides add \(17\) to both sides divide both sides by \(9\) will get you \(x\)

Best ResponseYou've already chosen the best response.0so I get 1=9x17 then 9 divided 18 = 2? so x=2?

Best ResponseYou've already chosen the best response.0how would I find y with this one?

Best ResponseYou've already chosen the best response.1then of course you have to find \(y\) but since you know \(x=2\) that should be easy

Best ResponseYou've already chosen the best response.1replace \(x\) by \(2\) in either equation if you want to check to make sure your answer is right, put \(2\) for \(x\) in both and see if you get the same number

Best ResponseYou've already chosen the best response.0is y=15? or y=3? I got a different answer when I pluged 2 into both problems /:

Best ResponseYou've already chosen the best response.1\[y=2x+1\] \[y=2\times 2+1=4+1=3\]

Best ResponseYou've already chosen the best response.1\[y=7x17\] \[y=7\times 217=1417=3\]

Best ResponseYou've already chosen the best response.1so you should get \(y=3\) for both, i am not exactly sure how you got the 15

Best ResponseYou've already chosen the best response.0okay now I see what I did wrong there, hmmm! thank you for showing both, I wouldn't have seen it if you hadn't!
