let's say, for example, I give this equation as an input:

4x + x - 20 + 10

And I want to get 5x - 10 as a result

DataMelt (http://jwork.org/dmelt) does this. Here is an example (I use Jython, but you can use Java too)

from jhplot.math import *  
from jhplot import *
j=Symbolic("jscl") # using jscl engine
print j.simplify("(x + 1)^(1/x)") == "(1+x)^(1/x)" 
print j.simplify("(x^2-1)/(x-1)") == "1+x"

This code returns "true" for all such simplifications

Maple does this well, but it is a commercial product.

For more alternatives check the List of computer algebra systems on Wikipedia, but that list does not show how something is implemented, or whether it has a Java API. You'd have to look this up yourself.
