Solving equation numerically



Hi,

I'm completely new to Maxima. I use it as a Mathcad replacement in
Linux which I am truly happy about. Today, I was in class given the
task to solve the given equation for x,

sin(x) + x = 2.5*x + 1.5

In Maxima I entered,

> solve(sin(x) + x = 2.5*x + 1.5, x);

which gives me,

x = 5 * sin(x) + 7.5

Isn't it possible to solve this equation numerically? I know that I
should get three results for x since there are three intersection
points. How do I solve this kind of calculation using Maxima?
