Hi, I'm new in electronic and I have problem with that circuit. I did what I can with that circuit and I stuck here. I have to calculate In but I don't know how. Could someone help me ?

You said you did what you can, but then don't show what you did. We aren't mind readers. Show your work.

You have this "U1" marked but don't give its polarity?

Is your dependent source a dependent voltage source or a dependent current source?

What are the units of the parameters in your nonlinear element? Is it 5 A² ? Is it 3 V/mA² ?

Are you familiar with Thevenin equivalents?

Are you familiar with load line analysis?

This is orginal picture what I get. The command says "Please find the value of the In current flowing through the nonlinear resistor in the circuit below."

I know Thevenin equivalents but only the basics and I don't know how to use it in that circuit. All I did was simplify the circuit

So look at how to find the Thevenin equivalent circuit when you have a dependent voltage source. It's pretty straight forward. Then find the equivalent for everything in your circuit except the nonlinear element.
