What must the emf E in the figure be in order for the current through the 7.00 - Ohm resistor to be 1.81 A? Each emf source has negligible internal resistance.(adsbygoogle = window.adsbygoogle || []).push({});

I solved for I through the 3-ohm resistor using the outer loop: 24V - (1.81A)(7-Ohm) - (3 Ohm)(I) = 0 and got that I = 3.77. I don't know where to go from there, though. I tried using the two inner loops separately, as there are two unknowns (I through 2-Ohm resister and E), but they just cancelled out, so I don't know where to go now. Thanks a lot, all help is appreciated
