i' = 2, 5 A; i'' = 0.375A; i''' = -1A; --> i = 1, 875A. I performed 3 circuits, each one with only one source ON. I obtained these values. The final answer is in accordance with the book answer.

turn of the current source part was mistaken. KVl at i2 answer was wrong. The right answer: (2i2=i1+4 )may be

The question requests you to use the superposition principle. So you should have performed 3 circuits, each one with only 1 source ON, which is the correct method as explained in the very book.
