Best ResponseYou've already chosen the best response.1Use the elimination method :  Multiply the first equation by 4 and the second equation by 3 The terms in y will then become 12y and 12y so adding the 2 equations eliminates y The result will be an equation in x

Best ResponseYou've already chosen the best response.1This is the elimination method Both the elimination and substitution method are used to solve systems of equations  the elimination method is usually the easiest one.

Best ResponseYou've already chosen the best response.1 but you could do it that way  find x first  then y using substitution

Best ResponseYou've already chosen the best response.1since the 2 terms in x are positive you need to multiply first by 13 and the second by 7 not 7
