How to find the voltage labeled v(x) by Nodal Analysis?
The sum of currents from node 2 to node 0 is equal to 0. However, I do not know the the current of 0.1Vx. How to solve the question?
Thank you for your help.

Since it is voltage controlled current source, the current from node 0 to 2 is 0.1Vx. Here replace Vx = V2-V3. So the last equation is :
$$ (V_2-V_1)/2 + (V_2-V_3)/4 - 0.1V_x =0 $$ $$ =>(V_2-V_1)/2 + (V_2-V_3)/4 - 0.1(V_2-V_3)=0 $$
Solving this equation, you would get V2, since V1=50V & V3 =100V
