Maybe I didn't get you right, maybe my skills in complex math are too limited, but what would you say is the correct and unique solution here?

What I see is x + (–0,5+0,86603 i)y = 30 i, which simply leads to the relation x = 30 i + (0,5–0,86603 i)y.

Thanks for the responses. For solving these equations you can break the real and imaginary parts into 2 equations. (assuming x and y are real, sorry should have stipulated that)
So the real part ends up being x -.5y =0
And the imaginary part is 0x + .86603y = 30

That is a bummer about not being able to use the solvers in a program. Guess I'll just roll my own extracting the real and imaginary parts into Cramer's rule

All in all though I have to say I am very impressed with the 35s. Much more powerful than the other calculators permitted on the FE exam.
