ob-calc returns the top element of the stack when finished and this will
be the result of the last operation in the src block.  I don't think
there's any way around this.

I use embedded Calc for this reason.  You could rewrite your equations
as simple lines (separated by empty lines from the surroundings) and
evaluate each in turn with "C-x * u":

fsolve(x 2 + x = 4, x) => x = 1.33333333333

fsolve([x + y = a, x - y = b], [x, y]) => [x = a + (b - a) / 2, y = (a - b) / 2]

I added the "=>" at the end of each expression so that the result is
shown to the right instead of replacing the expression itself (default
embedded Calc behaviour).
