1. The problem statement, all variables and given/known data
In the circuit below: (a) Find the current I1 that passes through the 7.5 Ω resistor.
2. Relevant equations
3. The attempt at a solution
This was a problem in my textbook. The answer is .65 A, but I don't understand how to get that. I tried Kirchhoff's rule by finding equivalent R between A & B and Then finding equivalent R between A & C then finding I, Then breaking I into I1 and I2 (according to the parallel resistances between A & B)
However, I still didn't get the answer, .65 A. Was my approach correct, or is there another way? Thank you.

Your plan of how to solve it is OK, and when I did it that way I got 0.65A.
If you can't find your mistake, show your working, then somebody can check through it.
