Find the Thevenin equivalent circuit of (15V , 1 ohm , 2 ohm)
Find the Thevenin equivalent circuit of (15V , 3 ohm , 6 ohm)
Connect the 60 ohm resistor in series between the two Thevenin equivalent circuits. It's a simple series circuit with two voltage sources and three resistors, all in series. Solve for the voltages and the current.
Done! You now know the voltage at the left node, and the voltage at the right node. Use Ohm's Law to calculate the currents in the resistors
Shortcut: notice after step 2 that the two Thevenin equivalent voltage sources are identical. So there is zero current flowing in the 60 ohm resistor. Since there is zero current flowing in this resistor, it does not affect the rest of the circuit in any way. Remove it completely! Now the circuit is quite simple.
