One place to start is to draw the circuit and label the three currents that flow in the three branches.
For example, draw an arrow beside the 5.1 ohm resistor and label it I1. Then draw an arrow beside the 10.3 ohm resistor and label it I2. Then draw an arrow beside the 4A current source and label it I3.
I say three branches because I am ignoring the current source on the right and R1.
Then post your drawing here.
