given this circuit find the current on R1,R2 and R2

2. Relevant equations

I = V/R

3. The attempt at a solution

i applied kirchhof's law and I have this:

36 - 5*I - I1*4 = 0

36 - 5*I + 20 - 2*I2 - 14 = 0

20 - 2*I2 - 14 + I1*4 = 0

and i find I1 = 66/19 which is wrong

the book says

I1 = 1.10 A

I2 = 5.21 A

I = 6.32 A

what am i doing wrong?
