Find The current through each of the resistors (see graphics) V=IR I would like for someone to please check my work to see if I have set it up correctly. No need to check actual values. Thank you!!!! Any and all help, tips, comments, suggestions, are appreciated!!!!

I am not happy with the signs in eq.(2). For the direction you chose for i1, it should be opposed to the 12-V battery. The equation above eq.(2) looks ok, so check the steps between the two equations.

Then including the equation at the top of the page, you have a system of 3 eqs. in 3 unknowns.

[I would have chosen the direction of i1 to the left so that the result would be positive.]

Thank you very much for your advice!!!

I see your point about the directions... Thanks for pointing that out.
