Homework Statement



Find the voltage across R1 (see attached image).

Note that all values are known.


Homework Equations



Voltager divider might be used. I hope KVL doesn't have to be used here.

The Attempt at a Solution



My problem is that I don't know if the current from I1 is going into the path in which there is R3, because there would be current in the opposite direction (downwards) coming from I2. Do I need to use such anaylses as Thevenin or mess analysis to find the current through R1?

I'd just use KCL equations.
