My equations, where x=I1, y=I2, and z=I3:

This outputs I3=-3i, I2=0. I can't see how this is correct.

Link to the equations on wolfram alpha: http://www.wolframalpha.com/input/?i=solve+x%3D5%2C+0+%3D+-5i+%2B+%28y-x%292i+%2B+%5By-z%5D5%2C+0%3D%5Bz-y%5D5+%2B+%5Bz-x%5D%5B-3i%5D+%2B+%5Bz%5D3i+for+z

Can anyone help me find my error? I don't have the solutions but I think its wrong. Thanks.
