(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

In the pictured, the battery puts out 12 volts, R1 is 9 ohms, R2 is 6 ohms, and R3 is 5 ohms.

What current flows through resistor R1?

Please use only SI (metric) system units in your answer!

2. Relevant equations

R=V/I ???

3. The attempt at a solution

I am completely lost...
