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.
