Can a CASIO CFX-9850GB Plus calculator solve simultaneous equations involving complex numbers?

Q: Hi, I own a CASIO CFX-9850GB Plus calculator and would like to be able to use it to solve simultaneous equations involving complex numbers. While I can call up the “i” in run mode:

OPTN, CPLX, i

I cant do the same in the solver mode or in the matrix mode.

Is it possible? If it’s not, can you recommend a calculator that can do this?

Cheers,

Thomas
