Explanation / Answer

Here ,

Using KCL at the left node

I1 - I2 - I3 = 0

Using KVL in the upper loop

10.5 - 3 I2 - 6 I1 = 0

in the lower loop

43.5 - 2 * I3 - 6 * I1 = 0

solving the equations

I1 = 4.20 A

I2 = -4.92 A

I3 = 9.125 A

part A)

I1 = 4.20 A

part b)

I2 = -4.92 A

part c)

I3 = 9.125 A
