What I need is for Mathematica to transpose the formula giving as out put x = 14/7. I beginning to believe that mathematica can't do it because the designer didn't put that capability in it. This must be a hard concept for a computer to do. It just seems simple to me. What's wrong with "out[1]= {{x -> 14/2}}" Which output I can't seem to get.

You must have missed my previous reply. See

So, what about using HoldForm as in,


In[1]:= Reduce[7 x == HoldForm@14]

Out[1]=

      14
x == --
      7
