Holy current, how do you find the the current at each ammeter?!?!

1. The problem statement, all variables and given/known data
Find the current at each ammeter.

My solution
Someone told me to use
$$\sum$$E-$$\sum$$IR=0
to solve the system but they weren't sure.

### Snazzy

Use Kirchhoff's junction and loop laws.
The sum of the voltage differences around any closed loop equals to 0.
The current entering a junction equals the current exiting a junction.

The person that told you to use:

$$\sum{E}-\sum{IR} = 0$$ is partially correct. You need to use that (it's called Kirchhoff's Loop Rule).

You also need to use Kirchhoff's junction rule $$\sum{i_{in}} = \sum{i_{out}}$$.
