Use both of Kirchoff's laws.
*But be aware that an arbitrary application of Kirchoff's two
equations will not always yield an independent set of equations.*
But the following approach will probably work.

- Label the current in each branch (do not worry about the direction of the actual current).
- Use only interior loops and all but one node.
- Solve the system of algebraic equations.
