Solve i_x when a=2. (See attached picture)

This is my attempt (mesh current analysis):

I made i1 be the lower left loop current.

I made i2 be the lower right loop current.

I made i3 be the upper loop current.

Using those last three equations:

I don't think that i1 can be 0... and I can't figure out any place I went wrong; it seems pretty straightforward?

Thank you very much for your help!

**Mesh1:**i1 = 2ix**Mesh2:**-10 + 3(i2-i3) + 20i2 = 0**Mesh3:**-5 + 3(i3 - i2) + 10(i3-i1) = 0**Also:**ix = i3 - i2 => -i1 - 2i2 + 2i3 = 0Using those last three equations:

__i1=0, i2=.5, i3=.5__I don't think that i1 can be 0... and I can't figure out any place I went wrong; it seems pretty straightforward?
