Best ResponseYou've already chosen the best response.0Add those 2 equations and y will be eliminated and you get the value of x. Substitute the value of x in any equation and find y. Once you get the value of x and y, then the solution will be of the form (x , y)

Best ResponseYou've already chosen the best response.0no direct answer ing allowed... but we can guide you :) first add the two equations together. Noticed that a variable will cancel out

Best ResponseYou've already chosen the best response.0Look at the y. One y is +y and the other y is y y  y = 0 so we get ride of the y \( x = 3k \) \( x = k \) Now add those

Best ResponseYou've already chosen the best response.0x + x = 2x 3k + k = 4k Now we have \(x = 3k \) \(x= k \) \( 2x = 4k\) Now divide by 2 and what do you get for x?

Best ResponseYou've already chosen the best response.0dw:1437570395517:dw then plug x = 2k back into the equation (one of them) dw:1437570428355:dw so x = 2k and y = k (2k,k)
