Best ResponseYou've already chosen the best response.1now we use a method to find x and y? which do you like ^^ elimination? substitution?

Best ResponseYou've already chosen the best response.1awsome (so much easier) x + 5y = 30 x + y = 14 we subtract x from x vertically. 4y = 16

Best ResponseYou've already chosen the best response.1we use the elimination then we sub y into the equation

Best ResponseYou've already chosen the best response.1if we did substitution we would make y the subject then get y THEN we would sub y into equation to get x

Best ResponseYou've already chosen the best response.1good so we can conclude x = 10 and y = 4

Best ResponseYou've already chosen the best response.1well there is some $1 and $5 bills yea... and they add to 14. we said that $1 is x and $5 is y. so x + y is equal to 14.
