I found z by using the equations 1 and 3 and it doesnt tell i need help with x and y
 2 years ago

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
ok i see it you can get the value of z using first end 3rd equation so how and how many you have got for z ?

i got z=3 and i know the answer for y is 1 and x is 4 but i dont know how to get them

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
yes z=3 is right sure so than this value of z=3 you can using there in first and second equation so than what will get if you us this value of z there ? what will get for first equation and what for second ?

how do you figure this out? i feel like an idiot right now

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
in the first equation assun to both sides 3 and will get how many ? so and for second equation multiplie 4 by (3) and will get how many ?

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
so you dont wann making the calcules here for ?

12 for the second equation?
 2 years ago

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
but how will be firstly the first equation ?

3x+2y=10 do you understand how i have got this result ?
 2 years ago

whadduptori Group TitleBest ResponseYou've already chosen the best response.1
oh okay! you added plus three to the 7? and so the 3 crosses out then?
 2 years ago

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
yes sure so than how you get the second equation ?

5x+5y12=9
 2 years ago

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
equal 3 and not 9
 2 years ago

whadduptori Group TitleBest ResponseYou've already chosen the best response.1
okay so what do i do after that?
 2 years ago

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
so will get 5x+5y12=3 so now add to both sides 12 and will get ????

5x+5y=15
 2 years ago

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
yes so now there are two equation 3x+2y=10 5x+5y=15 yes ?
 2 years ago

whadduptori Group TitleBest ResponseYou've already chosen the best response.1
okay! got it so far
 2 years ago

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
can you solve these system for x and y ?
 2 years ago

whadduptori Group TitleBest ResponseYou've already chosen the best response.1
yeah let me work it out
 2 years ago

whadduptori Group TitleBest ResponseYou've already chosen the best response.1
ok now im confused
 2 years ago

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
3x+2y=10 5x+5y=15 so first of all how do you see what can you factorizing out in the second equation ?
 2 years ago

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
why 15 ? and why not just 5 ???
 2 years ago

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
yes 5 right so than how will be the second equation ?
 2 years ago

whadduptori Group TitleBest ResponseYou've already chosen the best response.1
im sorry what do you mean?
 2 years ago

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
5x+5y=15 i have wrote above that you can factorizing out the 5 from the both sides but i mean that you can divide both sides by 5 and so will get 5x+5y=15 /5 x+y=3 ok ?
 2 years ago

whadduptori Group TitleBest ResponseYou've already chosen the best response.1
okay i see what your ssaying
 2 years ago

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
so than now there are 3x+2y=10 x+y=3 can you solve it now ?
 2 years ago

whadduptori Group TitleBest ResponseYou've already chosen the best response.1
what will you solve first the x or y? do you need to get rid of one?
 2 years ago

whadduptori Group TitleBest ResponseYou've already chosen the best response.1
i got it! i got the answr for y! y=1
 2 years ago

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
3x+2y=10 x+y=3  y=3x than this substitute in place of y in the first equation 3x+2(3x)=10 3x+62x=10 x+6=10 x=106 x=4 ok ?
 2 years ago

whadduptori Group TitleBest ResponseYou've already chosen the best response.1
ah thats why i just for x! i get it thank you!
 2 years ago

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
so than 4 +y=3 y=34 y=1 so than result that you have got it right ok ?
 2 years ago

whadduptori Group TitleBest ResponseYou've already chosen the best response.1
yup! thats what i did, thank you so much
