Question: Problem with solution due to RootOf

y = g/(1+exp(-a-i*c))+h/(1+exp(-b-i*d))

I cannot solve this for i. When I use maple I get a big result with a RootOf function that I don't know how to handle. I've looked around and I cannot find anything that will help me.

 

Can someone please show me how to solve this?

 

Thanks!
