You can use Part ( [[]] ) or Flatten. Part gets at the inner list, Flatten removes the nesting of the list: In[10]:= soln = Solve[2x + 6 == 27, x] Out[10]= 21 {{x -> --}} 2 In[11]:= somevar = x /. soln[[1]] Out[11]= 21 -- 2 In[12]:= somevar = x /. Flatten[soln] Out[12]= 21 -- 2 Tom Zeller Wolfram Research Technical Support. >Hi, >I was wondering if anyone could tell me how to deal with this problem. >I want to assign the numerical result that I obtain from the Solve or etc. >command, which typically enclosed in the braces ({...}) to a variable >so that I can reuse it.
