Best ResponseYou've already chosen the best response.0i dont know how. van you explain?

Best ResponseYou've already chosen the best response.1think of 2x+2y as 2y+2x what operation will undo that +2x ?

Best ResponseYou've already chosen the best response.1so we will have 2y = 8  2x which is the same as 2y = 2x + 8

Best ResponseYou've already chosen the best response.1we want to isolate y fully so we have to move that 2 (from 2y) over to the other side. How do we do this?

Best ResponseYou've already chosen the best response.1divide both sides by 2, yes

Best ResponseYou've already chosen the best response.1you have to divide EVERY term by 2, not just the 8

Best ResponseYou've already chosen the best response.1since it works like this \[\Large 2y = 2x + 8\] \[\Large \frac{2y}{2} = \frac{2x + 8}{2}\] \[\Large \frac{2y}{2} = \frac{2x}{2} + \frac{8}{2}\] \[\Large y = ??\]

Best ResponseYou've already chosen the best response.1you should divide 2x by 2 to get ????

Best ResponseYou've already chosen the best response.1nope not x, you are thinking of 2x divided by 2

Best ResponseYou've already chosen the best response.0isnt that the same thing??

Best ResponseYou've already chosen the best response.1so we will have y = x + 4

Best ResponseYou've already chosen the best response.12x + 2y = 8 turns into y = x + 4 when you solve for y

jim_thompson5910

Best ResponseYou've already chosen the best response.1so y = x + 4 and 2x + 2y = 8 are equivalent (ie the same exact equations)
