Did you really spend any time examining the documentation for Mathematica to learn the basics? It doesn't make sense to say "evaluate" the equation. Surely you want to "solve" it, for x. So why not look up Solve in the documentation. And be sure to look up the difference between the equality sign for an equation, the double-equal symbol ==, on the one hand, and the assignment (Set) single-equal symbol =, on the other hand. news.east.cox.net wrote: > I'm using Mathematica 5.1 I want to evaluate a simple equation > symbolically, such as 7x = 14. of course the answer should be x = 14/7. > I can't find a clear example on how to do this with a simple equation. > Can anyone help me? > TIA > Paul > -- Murray Eisenberg murray at math.umass.edu Mathematics & Statistics Dept.
