Best ResponseYou've already chosen the best response.0Like if you take off the ;x=2,1,3 it has the 2y+4x+8;x

Best ResponseYou've already chosen the best response.02y+4x+8 is an expression. you cannot solve an expression ,only find its value at a particular 'x' and 'y'. did you mean 2y = 4x+8 ?? and need to find the value of y for x= 2,1,3 ?? if possible , you can post the screenshot of the entire question, so we can help :)

Best ResponseYou've already chosen the best response.0The way it is in the book is like this 2y+4x=8;x=2,1,3

Best ResponseYou've already chosen the best response.0ok,so now i think you need to find 'y' values. can you isolate 'y' from 2y+4x= 8 ? that is bring it in the form y=....

Best ResponseYou've already chosen the best response.02y+4x=8 divide entire equation by 2, what u get ?

Best ResponseYou've already chosen the best response.0So isnt it going to be 4x=82y?

Best ResponseYou've already chosen the best response.0let me give u an example, if you had 6y+2x=10 and if you wanted to divide entire equation by 2, you would get , (6/2)y + (2/2)x =10/2 which is 3y+x=5 , an equation. so what do u get for 2y+4x=8 ?

Best ResponseYou've already chosen the best response.0So isnt it going to be 4x=82y? then 4x/4=(82y)/4 then answer is x=(82y)/4

Best ResponseYou've already chosen the best response.0but here, you need to isolate y, you actually isolated 'x'. can you try to isolate 'y' similarly ?

Best ResponseYou've already chosen the best response.0Nope i just know how to do the 'x'

Best ResponseYou've already chosen the best response.0thats why i asked you to divide both sides by 2 first and gave you an example, see that and tell me what u get after dividing 2 on both sides of 2y+4x = 8

Best ResponseYou've already chosen the best response.0alternatively, you can subtract 4x from both sides first...

Best ResponseYou've already chosen the best response.12y + 4(2) = 8 2y + (8) = 8 2y = 8+8 y = 16/2 y = 8  2y + 4(1) = 8 2y + 4 = 8 2y = 84 y = 4/2 y = 2  2y + 4(3) = 8 2y + 12 = 8 2y = 128 y = (4)\2 y = 2

Best ResponseYou've already chosen the best response.1sorry to say...just substitute it....for x....
