A problem about "dirty money"

[VinnyCee]

A 3.0 kg box of dirty money is on a frictionless plane inclined at 30 degrees attached to a 2.0 kg box of laundered money also on a frictionless plane on the other side at an angle of 60 degrees. What is the tesion in the cord?

I have been trying to figure this one for about 4 hours.

is the system moving at an acceleration...? or is it at a constant velocity... in either case I believe you just add up the horizontal forces which woud be the normal force on one side - tension = the same on the other side if its not moving...
