Best ResponseYou've already chosen the best response.2okay so when you have questions like these, there are two methods you can go to; substitution method and elimination method do you know how these work?

Best ResponseYou've already chosen the best response.2okay so if you want to substitute, write either one of the two equations in the form of y = ... or x = ....

Best ResponseYou've already chosen the best response.2okay so say we pick the first equation and want to write it in terms of x... so 3x + 3y = 10 we want to isolate x, do you have any ideas how we may do so?

Best ResponseYou've already chosen the best response.2um no, we want x by itself, so we can start off by subtracting 3y from both sides of the equation, to get 3x + 3y  3y = 10  3y and now we simplify..

Best ResponseYou've already chosen the best response.2so we get 3x = 10  3y

Best ResponseYou've already chosen the best response.0can it also be 3x=3y+10?

FireKat97

Best ResponseYou've already chosen the best response.2no because we subtracted 3y from the right hand side, we didn't add it

FireKat97

Best ResponseYou've already chosen the best response.2because only through subtracting 3y from both sides, could we cancel 3y on the left hand side and try to isolate the x

Best ResponseYou've already chosen the best response.0so we divide 103y by 3x? @FireKat97

Best ResponseYou've already chosen the best response.2close.. we divide it by 3 alone :)

Best ResponseYou've already chosen the best response.2that way we get x = (10  3y)/3

Best ResponseYou've already chosen the best response.0\[x=\frac{ 103y }{ 3 }\]

Best ResponseYou've already chosen the best response.2yup thats correct! Now we want to substitute this into our second equation and simplify..

Best ResponseYou've already chosen the best response.0\[9(\frac{ 103y }{ 3 })9y=30\] so tht? @FireKat97

FireKat97

Best ResponseYou've already chosen the best response.2Yup! thats right! now we have to simplify

Best ResponseYou've already chosen the best response.0\[9(\frac{103y }{ 3 })9y=30\] \[21y9y=30\] \[+9y+9\] 30=30 @FireKat97

Best ResponseYou've already chosen the best response.2umm let start off by opening and simplifying the brackets first, so just simplify 9(10  3y( and tell me what you get
