I have the following circuit....(adsbygoogle = window.adsbygoogle || []).push({});

I have managed to derive an equation for U2:

Now I want to substitute U2 into U1, in order to derive equation for U1

I have defined U1 as:

Now I substitute U2 into the above equation. This is how far I get.....I am stuck...

My circuit simulator is saying that U1 is equal to:

However I cannot simplify to get this equation. Can someone please help I have spent hours trying to get U1 to look like the U1 that the simulator produces.

I thank you in advance.
