can we say that because the determinant of the matrix is 0, z+iy=0 so z-iy will also be 0 because z-iy is nothing but z+iy-2iy , Idk what I am saying T-T can someone please explain?
in the solution it is given by comparing the complex equation with 0

I think after this we need to assume y=0 and hence, answer will be 0
yeah, if z=-iy then z-iy will be.. No, I think this approach is bad :/
:/ i guess so
