When Diode is on Vd=0.7 V and Id=0

When Diode is off Vd<0.7 and Id>0

3. The attempt at a solution

I've been working on this problem for hours now but I just can't logic it out properly. I know the right model is supposed to be D1 ON and D2 OFF, but I can't figure out why or what the value of Vx is. Any help would be greatly appreciated.
