Determine I_1 I_2 I_3

When

E = 15V

R1 = 20k ohms

R2 = 4.7k ohms

R3 = 10k ohms

2. Relevant equations

KCL equation

3. The attempt at a solution

i tried to find using KCL.. is my equation right?

Loop equation 1:

EB + I3R3 + R1(I3 + I1) = 0

Loop equation 2:

R1(I1 + I3) + R2(I1 – I2) = 0

Loop equation 3:

EB + I3R3 + I2R2 = 0

can i use MESH analysis... but there are three unknowns and if i use mesh, i can only have 2 equations with 3 unknowns
