I have figured out A_y and E_y by finding the resultant forces of the distributed loads, then taking the moment about A to get E_y, then summing the Y-forces to get A_y.
I got E_y=7560#, and A_y=3240#.

Now, I know I need to make a cut, but I do not know where/how to take it. Do I cut vertically at C? and if I do, does that expose a horizontal force in member BE? Or do I cut just to the right of B? What is the next step?
