(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I need to find the current equation for the junction in node a in the following circuit:

2. Relevant equations

Current in = Current out so I(in)=I(out)

3. The attempt at a solution

The arrows in the diagram represent the direction of the current.

At node a I thought the junction rule would be

I(3)=I(2)+I(1)

Is this wrong?

I think it is but I don't understand why!?

Please help!
