I need the thevenin equivalent to this circuit, I've calculated Eth and Rth but i don't think my answer is correct

Hello mec, please use the template to show us what expressions / equations you have available to deal with this exercise. And show us your work. Eth, Rth. And why you think your answer is not right.
In short: use the template

1. Homework Statement
Find the Thevenin equivalent circuit at terminals (a,b) of the circuit:


2. Homework Equations

Eth= E
Rth= (R4+R5)//R3 +R1

3. The Attempt at a Solution
so Eth=2v and Rth= 3.66 ohm

the reason why I think the answer is not correct is that i have not studied Thevenin for a long time :)

It would help if your drawing were readable, but it appears that your analysis of the resistive network makes no sense at all. I can't be positive of that because I can't really read the diagram.
 
Start with Eth. Assume Rc is infinite and calculate the voltage over Rc.
Continue with Rc = 0. Assume Rc is zero and calculate the current through Rc.

[edit] Oh, and if studying something is a problem, sometimes Googling is enough nowadays. The Wiki thing is crystal clear,,,
