sorry about that so by addition you get \[2y=1\] thus \[y=1/2\] There are two answers since both equations have a high power of 2 so y=1/2 and y=1/2 now both equations are \[x=9/2\] so \[x=3\sqrt{2}/2\] and \[x=-3\sqrt{2}/2\] so the answers are (\[3\sqrt{2}/2\],1) and (\[-3\sqrt{2}/2\],1) there's your answer, sorry the formatting is screwed up
