I'm probably wrong in this but I suppose y = any real number and x= all real numbers excluding zero? since a fraction can never have a zero.
... then first note that x cannot be 0.
substitute any other value of x and determine the corresponding value of y.
also, note that there are an infinite number of ordered pairs (x,y) that satisfy this equation.
to get specific solution(s), you'll need a second equation that relates x and y.
