Find the currents through the circuit using Kirchoff's law and Supersposition theorem. Initially consider each loop and apply KVL to it. You will get equations with some unknowns for the currents. Solve them as you would solve simultaneous equations and solve for the unknown currents. Alternatively you an use superposition theorem. Short one source and solve for the currents and then short the other source and solve for the currents again. You will get two sets of current for each resistor from both the sets of equations for each source. Add them to get the total current for each resistor. Verify with the given circuit practically.
