^tamago^ SG http://forums.hardwarezone.com/showthread.php?t=1397546 graph as shown: but how to do on paper?
^tamago^ SG bo bian. i got a line as a solution, but pian pian the grapher shows the answer as 3 points (-2,2), (0,0), (2,-2)..... i very hardworking one k.
^tamago^ SG anyway solved liao~ can close liao~ more solutions read the link above~ i forgot to sub back... kns~
^tamago^ SG leave a copy here. (x²+y²-6)/(xy+5) = -2x/y --- from (1) (x²+y²-6)/(xy+5) = -2y/x --- from (2) then x/y=y/x. then x²=y². then y=x or y=-x. sub back to (1) and (2) to get (-2,2), (0,0) and (2,-2).
