Does anyone understand the solution to this one? Does the problem have to be converted into a Y equivalent to solve for Vab?

There's another post about this - it is detailed and should help you. To generalize, I think YES you do need to treat it like a Y connected source so you can analyze it on a L-N basis. :)

 
Here is another way to look at the problem using KVL around the a closed loop. See attached.

thanks for everyone's help.
