My loop 1 equation is I1R1 + I2R2 + E1 = 0
simplified to: 4I1 + 2I2 + 28 = 0
Loop 2: I3R3 - E2 - I2R2 = 0
simplified to: 1I3 - 7V - 2I2 = 0
And my node 1 equation is: 0 = I1 + I2 + I3
So doing algebra.. I get my I1 to equal 7.. which doesn't match with the -5A for I1 as given in the problem.
Are my equations wrong? Or is my algebra wrong?
