I was calculating a conditional density function and I got an answer of 2x+3y all over 2x+3/2.  When I checked the answer, it was 4x+6y all over 4x+3.   Those two answers are the same, but my question is--is there some protocol as far as what is proper form to express an answer in when dealing with density functions?
