What's the current through the 2Ω resistance? The question requires me to find the answer by using Thevenin's theorem
As a hint, consider that your circuit behaves exactly the same as this one:

Now you should be able to see how you can apply Thevenin's theorem (two times) to simplify this circuit to the point where you'll be able to find the current through R5 by inspection.
