Thevenin's equivalent circuit problem

[backstance]

Homework Statement

use thevenin's theorem to find the current in the 3 ohm, parallel branch, resistor

Homework Equations

Thevenin equivalent circuit, voltage divider rule

The Attempt at a Solution

I don't think its possible, since thevenin's theorem ends up with a voltage source and a resistor in series, you can only find currents and voltages in components that are in series. In this circuit there is nowhere to make the cut and split the circuit across terminals A and B. Normally you'd need Norton's equivalent circuit to find the current in the 3ohm resistor. Am I right, or is there actually a solution using thevenin's?

Could anyone solve this problem?

try and study it from the url. The circuit is quite the same as yours.
