find the transfer function H(s)

[PLAIN]http://img192.imageshack.us/img192/4204/asdwoe.jpg [Broken]

2. Relevant equations

H(s) = Vout/Vin

done in the frequency domain so: C1 and C2 turns into 1/sC

where C1 = C2 = .1F

and R1 = R2 = 20

3. The attempt at a solution

to find the transfer function, i have to apply an impulse source. therefore, Vin is just 1V.

my attempt at this by using node voltage method:

(Vx is the node that connects R1, R2, and C2)

(Vx -1)/20 + Vx/(10/s) + (Vx - Vout)/20 = 0

i am stuck with two unknowns and 1 equation. :[
