Do you mean something like: In[11]:= Solve[{a == x + y, b == x*y}, {b}, {y}] Out[11]= {{b -> (a - x) x}} or In[12]:= Solve[{a == x + y, b == x*y}, {b}, {x}] Out[12]= {{b -> (a - y) y}} ? -- Andrzej Kozlowski Toyama International University JAPAN http://platon.c.u-tokyo.ac.jp/andrzej/ http://sigma.tuins.ac.jp/ on 01.4.29 10:35 AM, Jesse Marder at yarblocks at yahoo.de wrote: > Hello. > > I have for example: > > a = x + y and > b = x*y > > whats the procedure to express b as a function of a in Mathematica? > > Thank you. > Jesse. > >
