Let x be the voltage at the junction of 10v 20v and 1 ohm respectively.
Apply KCL at the junction.
(x-10)/2 + (x-0)/1 + (x-20)/4 = 0
(2x – 20 + 4x + x – 20 ) = 0
7x = 40
x = 40/7
 
I = (40/7 – 10)/2 => -30/14 = -15/7A
 
minus sign indicates that the current is flowing in the opposite direction of that assumed.

							Dear Student,
Please find below the solution to your problem.

Apply KCL at the junction.
(x-10)/2 + (x-0)/1 + (x-20)/4 = 0
(2x – 20 + 4x + x – 20 ) = 0
7x = 40
x = 40/7
I = (40/7 – 10)/2 => -30/14 = -15/7A
