Question: Using solve function with Complex numbers ?

Hello,

Questions,

Can I use the solve function with complex number?

i.e) a simple example

7 = solve(magnitude((2+j7) / (1+j*x), x)

How to implement the above to solve x in Maple?

seems Maple doesn't treat the complex sign of j as complex.

ie)
solve(sqrt(5)=abs(1+k*I), k);

I got k as
-I*(5^(1/2)-1), (5^(1/2)+1)*I

I might expect the k for 2.

Thanks,
