Respuesta :

py+7=6y+q does not involve division.  What type of fraction form are you thinking of?

py+7=6y+q could be rearranged:  py-6y = q - 7, or y(p-6) = q - 7
                    q - 7
Then y = ------------  This is y in terms of p and q.  But again, I don't know  
                    p - 6     whether this is what you were looking for.  
                                 Please be more specific.
