I am trying to solve and algebraic expression of form f(x)=a.
Where I already know the value of a now I want to find out value for x.



One of the API which I tried is exp4j but I can only find the value of function if I provide the value for x. Not sure if reverse if possible with that exp4j



For Example:
I have: x*1/40+5=12
Now I want to solve for x like below:



x=(12-5)*40

x=280


How do I solve this in Java where a string like this x*1/40+5=12 is taken as input and gives out value for x.

  • Try looking at logic programming languages. Take a look at Prolog. There are a few popular java integrations or similar language integrations.
