Kirchoff's Equations

1. The problem statement, all variables and given/known data

Write six equations using the unknown currents I1, I2, etc.

Circuit included as attachment.

2. Relevant equations

Ohm's law

3. The attempt at a solution

So I1, and I3 are fairly straightforward.
$$I_{1}=\frac{X}{R_{1}}$$
and
$$I_{3}=\frac{X}{R_{3}}$$

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.

Perhaps they want you to use Kirchoff's laws, as suggested by the problem title?

Hint: Kirchoff's laws involve the various loops and nodes within the circuit.
