Best ResponseYou've already chosen the best response.0well yeah i did that multiplying it by 2 so that when i add it in the second question 14x and 14X cancel out (I'm using linear combinations here)

Best ResponseYou've already chosen the best response.0In the first equation you do 2y times 2 = 4y. Now in the 2nd equation you have 4y soo 4y+ 4y is 8y which means that the ys don't cancel out
