What’s the simplest way to solve an algebraic equation in the complex domain?

 

For example,

 

I*(a+3*b)+2*b+5*a = 3+2*I

 

where a and b are real numbers.

 

 

 

 

How can I know the solution is correct??

 

Here is the code:

s := solve(sin(x^2) = 1/2);
test := subs(x = s[1], sin(x^2) = 1/2);

 

 

 “Error, too many levels of recursion” ,but there’s just a single expression.

 

 

How can this happen?

The help documents read,

 The function unames returns an expression sequence consisting of all the active names in the current Maple session which are ``unassigned names''.

 

But what unames() returns is obviously not the contents one expects:
