Ideal Op-Amp circuit Output voltage expression
YOu should be able to figure of Vo2, given only what you know about op-amps, feedback, and the currents.  Think about what the voltage must be on the positive input of the top op amp.  Once you have that, you have I1.  Once you have I1, you have Vo2.  

That should give you your current through both feedback resistors, which will lead you to Vo1
