If I am solving a simple equation, such as: Solve[z+2 = = 3,z], this
returns {{z->1}}. How can I easily get the result, 1? Solve[] returns
the solution in rule form.
The current method I use to just get the result looks very ugly. Is
there an easier way to do this?
Here is my current method:
ReplaceAll[z, First[ First[ Solve[ z + 2 = = 3, z ]]]];
z = %;
Now I can use z as a normal variable.
Thanks!
