Homework Statement:
 Nodal analysis
Relevant Equations:
 I in = I out
My attempt:
At node 1 > 4 = 6 + I1
Node 2 > I1 + I2 = I 2
Node 3 > 6 = I 3 + I 4
I1 = (V1  4)/21
In node 1,
Using the equation for I1, V1 = 38V.
I2 = (V1  4  1)/2
So, I2 = 21.5A
Power supplied by the 1V battery is
P=VI
P=21.5 x 1
P=21.5W
I am not sure of my method, I just started with Circuit analysis class.
Thanks.
