"Uncaught TypeError: Cannot read property '1' of undefined" on solveEquations #628

Hey jiggzson, We have quite a strange bug that happens when we call solveEquations with given array.

nerdamer.solveEquations(["0=discount___plan / (45909438.9 + 0 + discount___plan)", "45909438.9=45909438.9 + 0 + discount___plan"])

output

Uncaught TypeError: Cannot read property '1' of undefined

Here is an easier repro: nerdamer.solveEquations(["a=1"])

@sametaylak, thanks. I'll looking into it. @gunnarmein, thanks for the easier repro.
