Circuits (Nodal and loop anal. finding current through branch)

[Miike012]

I am trying to solve for i_sc. The correct answer is i_sc = 6mA but I got 0 mA.

My equations must be correct... If they are not please someone explain why.

Thank you.

That's a rather difficult image to read: sideways and illuminated through a partially open blind.

Your choices for i₁ & i₂ are not the most convenient.

It looks to me like:

I_x = i₂ = i_sc

and

2I_x = i₂ - i₁ .
