Hello, I want to develop the transfer function of the circuit shown bellow.
i want to develop a Vout/Vin expression, I wrote the equations as shown bellow.
I am stuck on te Vx stage.
how do i get rif of Vx and get a put vout/vin expression?
Thanks.

 

It appears that you are using an ideal opamp model, so what is the voltage at Vx going to be?
