Hi at all,

is there a easy way to solve a bunch of equations?
For example, on my hand calculator I can insert my 4 equations into a "solve"- function and get a solution for my 4 unknown variables.

How can I handle it with processing?
My 4 equations are:

(1) a1² + b1² = w²

(2) a2² + b2² = x²

(3) b1 + b2 = y

(4) a1 + a2 = z 

given: w, x, y, z

searched: a1, a2, b1, b2

I tried to solve it by hand, but it becomes too heavy for me.
For example:
I want to have b1:

z = sqrt( w² - b1² ) + sqrt( x² - (y - b1)² )

b1 = ...?

I was not able, even my hand calculator was not able to get b1 ...I'm searching for a better solution to do that in processing...maybe there is a solve- function or something like that...

hope you guys can help me :)
thanks
