Find the current in the 4.00 ohm resistor in the drawing [Solved]

6a 4 b = 9

6a 4 b = 9

Considering the potential equations
in the left loop

In the left loop
12b 4a = 15

In the left loop
12b 4a = 15

a = 0.86 A and b = 0.96 A and a b = 1.82 A
==========================

Explanations;
The assumed current a passes through both 2 and 4 , the sum of the potentials
= 6 a .
The assumed current meets the negative of the 6 V and 3V battery hence the potential is 6V 3V = 9V
The sum must be zero
6a 4 b -9 = 0
Similar explanation is for the other loop.
