Hi,

I am not sure to have fully understood what you are looking for, since 
the second argument of Reduce contains the list of variables for which 
you want a solution. (it is also useful for distinguishing variables 
from constant parameters.)

"Reduce[expr, vars] reduces the statement expr by solving equations or 
inequalities for vars and eliminating quantifiers. "

HTH,
Jean-Marc
