Is my doings correct sir?

I think i got the right kvl when you say that all the currents in the problem are moving away, because i always think that these directions are just a design and not to include in a certain circuit problem, i used to follow the notes of mine even if it has a different directions, so i think this...

So you're saying that my kcl is wrong, instead of I2=I1+I3, it should I1+I2+I3=0 and by transposing it we get -(I1+I3) = I2, is that correct?

To be clarify: The calculation i got first is this: V1-I1R1-I2R2-V2=0 5I1+10I2=6V+6V 5I1+10I2=12V 0.42I1+0.83I2=1 Second: V1-I1R1-I2R2-V2=0 6V-5I1-10I2-6V=0 5I1+10I2=0 Which is correct guys? i feel sorry to myself because i got this trust issue in my doings, and I am just asking about your...

This are the answers (a) 8.3 mN; (b) 3.5 mN.

Still finding the final formula for this problem
