I do not know how to find Vo in this circuit. According to my notes about how to take node voltage, I get

0 = Va + 6.857 V + 0V

Vo = Va

But that doesn't sound right. And I get a different answer using mesh, then using

Vo = V Across the 4k resistor

I would really appreciate the help! Thank you!

    \$\begingroup\$ Also, you give an equation using the term \$v_a\$, but you never said what \$v_a\$ represents. If we knew that, we might be able to point out where you went wrong. \$\endgroup\$ – The Photon Sep 28 '19 at 2:22

KVL is a law, not a suggestion. Trust Kirchhoff, trust your instincts. If you are getting a different answer using mesh analysis then we should take a look at your equations.
