1. The problem statement, all variables and given/known data Find Voltage V_0. There is also a dependent voltage source in the circuit I'm not sure what to do with. The two nodes on top are essential nodes and can be treated as one, same with both bottom nodes, but the bottom nodes I assigned them to be the reference node.

The attempt at a solution My node voltage equation : -3 + V/200 + (V-5i)/10 + (V -80)/20 V is V sub 0: V_0 and i is i sub delta i_Δ For the equation for i_Δ : would it be (v-80)/20 Again I'm unsure of how to handle the dependent source in this circuit.
