Homework Equations



Ohm's law

The Attempt at a Solution



So I1, and I3 are fairly straightforward.
[tex]I_{1}=\frac{X}{R_{1}}[/tex]
and
[tex]I_{3}=\frac{X}{R_{3}}[/tex]

Now I get confused. Because the voltage divides, I am unsure of how to attain the equations for the remaining currents without using the mesh current method.

Thank you for the help.

Edit, and now I realize that I3 is not X/R3, but rather I3=I1, but my confusion still stands about the best way to retrieve 6 equations.
