Best ResponseYou've already chosen the best response.1how you need to solve it with sustitution method or elimination method ?

Best ResponseYou've already chosen the best response.1I found z by using the equations 1 and 3 and it doesnt tell i need help with x and y

Best ResponseYou've already chosen the best response.1ok 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 ?

Best ResponseYou've already chosen the best response.1i got z=3 and i know the answer for y is 1 and x is 4 but i dont know how to get them

Best ResponseYou've already chosen the best response.1yes 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 ?

Best ResponseYou've already chosen the best response.13x+2y3=7 5x+5y+4*(3)=3 so can you make the calcule here ?

Best ResponseYou've already chosen the best response.1how do you figure this out? i feel like an idiot right now

jhonyy9

Best ResponseYou've already chosen the best response.1in 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 ?

Best ResponseYou've already chosen the best response.112 for the second equation?

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

Best ResponseYou've already chosen the best response.13x+2y=10 do you understand how i have got this result ?

Best ResponseYou've already chosen the best response.1oh okay! you added plus three to the 7? and so the 3 crosses out then?

jhonyy9

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

whadduptori

Best ResponseYou've already chosen the best response.1okay so what do i do after that?

jhonyy9

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

jhonyy9

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

Best ResponseYou've already chosen the best response.1okay! got it so far

jhonyy9

Best ResponseYou've already chosen the best response.1can you solve these system for x and y ?

whadduptori

Best ResponseYou've already chosen the best response.1yeah let me work it out

jhonyy9

Best ResponseYou've already chosen the best response.13x+2y=10 5x+5y=15 so first of all how do you see what can you factorizing out in the second equation ?

jhonyy9

Best ResponseYou've already chosen the best response.1why 15 ? and why not just 5 ???

jhonyy9

Best ResponseYou've already chosen the best response.1yes 5 right so than how will be the second equation ?

Best ResponseYou've already chosen the best response.1im sorry what do you mean?

jhonyy9

Best ResponseYou've already chosen the best response.15x+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 ?

Best ResponseYou've already chosen the best response.1okay i see what your ssaying

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

whadduptori

Best ResponseYou've already chosen the best response.1what will you solve first the x or y? do you need to get rid of one?

whadduptori

Best ResponseYou've already chosen the best response.1i got it! i got the answr for y! y=1

Best ResponseYou've already chosen the best response.13x+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 ?

whadduptori

Best ResponseYou've already chosen the best response.1ah thats why i just for x! i get it thank you!

jhonyy9

Best ResponseYou've already chosen the best response.1so than 4 +y=3 y=34 y=1 so than result that you have got it right ok ?

whadduptori
