Why don't you show us your work? Maybe someone can see where your error is.
Did you start with three separate simultaneous equations? Did you CORRECTLY isolate for x by adding or subtracting two of the three equations and applying the log function? Did you CORRECTLY isolate for y by adding or subtracting two of the three equations and applying the log function? ARE YOU APPLYING THE LOG FUNCTION CORRECTLY? Did you add the new equations together to create an x + y expression within an equation? Were you able to isolate the x + y expression? Were you able to manipulate the remaining algabraic expressions so that x + y = 1 ? Q.E.D. if you did.
