    HOW DID YOU MARK THE CURRENT DIRECTIONS.?

      The choice of current direction is arbitrary. The main thing is to keep the polarity of voltages or direction of current sources in mind while writing KVL and KCL equations.
      For instance, I chose current flowing from node 2 towards node 0, which is opposite from source with 14 amps so I20=-14 amps. I20 is current flowing from node 2 to node 0.
      If I chose current as flowing from node 0 into node 2, then I02=+14 amps. I02 is current flowing from node 0 to node 2.
      Hope this helps.
