Best ResponseYou've already chosen the best response.0x + y = 110 x  y = 28. what do you think? assume y<x

Best ResponseYou've already chosen the best response.0btw. x = 69,y=41. but don't look at the answer. find out why :) first.!

Best ResponseYou've already chosen the best response.0Well, it says which is the smallest of the two numbers, so I'd have to go with 41 because that is smaller.

Best ResponseYou've already chosen the best response.3Here's the trick: bigger number = (sum+difference)/2 smaller number = (sumdifference)/2

Best ResponseYou've already chosen the best response.0So it must be 41 because that is the smaller number.

Best ResponseYou've already chosen the best response.0RONNCC has a good answer, basically it is best to use substitution in order to solve. He said: "x + y = 110 x  y = 28. what do you think? assume y<x" and you may assume without loss of generality that y<x, since xy=28 > 0 meaning x>y. y=x28 from the second equation, so just substitute this into the first to give: x+x28 = 110 > 2x=138 > x=69. To find y simply use your first equation: 69+y=110 > y=41.

Best ResponseYou've already chosen the best response.0substitution is nice for harder equations, but generally elimination is a good method when the coefficient of x is 1 and they are in a simple form like this.
