Here is the problem:(adsbygoogle = window.adsbygoogle || []).push({});

The diagram below shows a circuit where; R1 = 2.00 Ω, R2 = 4.00 Ω, R3 = 8.00 Ω, V1 = 7.500 V, V2 = 10.00 V, and V3 = 8.00 V. (In solving the problems that follow, initially pick the current directions as shown. If the actual current turns out to be in the opposite direction, then your answer will be negative).

Using the junction and loop rules I came up with these equations but apparently something is wrong, please help me:

I1 + I2 + I3 = 0

-V1 + I2R2 - V2 - I1R1 = 0

I3R3 - V3 + V2 - I2R2 + V1 = 0

EDIT:

I know how to solve this problem in theory with the equations but when I did I got the wrong answer so I'm checking if my original equations are right
