Figuring Out Current Above the Junction: A Puzzling Problem

[happytailsgal]

Homework Statement

In the figure, what is the current in the wire above the junction?

Homework Equations

V=IR or I=V/R

The Attempt at a Solution

I am really confused as to what "above the junction" means. I tried to add the voltages and add the resistors and divide them to get the current and it didn't work. Then I tried to just do the top voltage and resistor (so it would be three) and that didn't work either. What am I doing wrong?

What does Kirchhoff's Current Law say?

Above the junction, current is labelled as I
