Transfer function of an op amp-amp circuit

Let's suppose the following circuit:

enter image description here

I am trying to find a relation between Vs, V1 and V2 atin this circuit. Please note that Vs is measured in relation to the ground. I have declared some extra points (A,B,C) on the circuit and using voltage divider laws and the properties of an ideal operational amplifier I came up with the following solution:

enter image description here

Is this correct?

Another solution with a different result is the following:   

enter image description here

I am really confused.
