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. wrote:
