Best ResponseYou've already chosen the best response.0no. these equations are already solved for y, so set them equal to each other to solve for x. 5x  9 = 2x + 6

Best ResponseYou've already chosen the best response.0ok. did you get a yvalue for the one above?

Best ResponseYou've already chosen the best response.0Isn't that the same as the x vaule?

Best ResponseYou've already chosen the best response.0not necessarily. when they say "solve the system" they're asking for a point that makes both equations true. that point will have an xcoordinate and a ycoordinate. Once you have the x, substitute it into either one to get y

Best ResponseYou've already chosen the best response.0what did you get when you solved that equation for x?

Best ResponseYou've already chosen the best response.0You can't add/subtract things on different sides of an equal sign. You can move things from one side to the other using addition or subtraction. Let's start by getting all the terms with x on the left side. To do that we need to eliminate 2x from the right side. Since 2x is positive, subtract 2x from both sides. dw:1435682067537:dw

Best ResponseYou've already chosen the best response.0Now you need to move 9 to the right side by adding 9 to both sides. Give it a try

Best ResponseYou've already chosen the best response.0right. x = 5. Now to get y, you have to substitute into either equation. y = 2x + 6 y = 2(5) + 6 = ?

Best ResponseYou've already chosen the best response.0yes, so the solution the system is (5, 16).

Best ResponseYou've already chosen the best response.0X= 5 and y = 16. Do i plug them back into the original equation?

Best ResponseYou've already chosen the best response.0those are the answers. You can plug them in to check.
