[realonly: true] doesn't work to [solve]



Hi all,

I want to get a real only solutions for the equation.. using
'realonly: true' and 'solve' such as below gave me all solutions
including complex one..

realonly: true;
solve([(1 + 2*x)^3 = 13.5*(1 + x^5)], [x]);

However.. using 'algsys' will do the job perfectly..

realonly: true;
algsys([(1 + 2*x)^3 = 13.5*(1 + x^5)], [x]);

Is it by design..?

Best regards,
