Solve a System of complex equatoins

[kitsunekatari]

Hey everyone, new here obviously. Just purchased an HP Prime, coming from a TI89. Still trying to get used to the new syntax and commands.

How do I solve a system of complex equations?

such as;

-12+(-i4+i5)*A-i3*B
(12+i6)*B-i3*A

In the ti8 it was csolve( {-12+(-i4+i5)*A-i3*B,(12+i6)*B-i3*A},{A,B} )

But this is not the case with the HP Prime. Thoughts?

Thank you!
