Best ResponseYou've already chosen the best response.1Ok, so \[2x4=4y?\]

Best ResponseYou've already chosen the best response.0Wait.. actually multiply the second equation by 4. That way you eliminate the x term

Best ResponseYou've already chosen the best response.1How would I subtract it from the first equation? X becomes eliminated than what?

Best ResponseYou've already chosen the best response.0When x is eliminated, you can find the y term

Best ResponseYou've already chosen the best response.1substitution method. (not elimination method) 4x + 2y = 11 x – 2 = – 2y (find 'x' from here, by adding 2 on both sides)

Best ResponseYou've already chosen the best response.0Once you find the y term, you can substitute it in any of the above equations, and then you get x.

Best ResponseYou've already chosen the best response.0@hartnn you'll still have the y term

Best ResponseYou've already chosen the best response.1x – 2 = – 2y x = 22y plug this in 1st equation 4(22y) +2y =11 simplify and get y

Best ResponseYou've already chosen the best response.0@hartnn , but can't you solve it using elimination as well?

Best ResponseYou've already chosen the best response.1the system can be solved by elimination method, but since the question specifically asks for substitution, we need to use substitution
