The solution method depends a little on what you are solving for, and whether you want a transient or a steady-state solution. I assume because there is "only one battery" that it is a DC circuit and you want a steady-state solution.

In the general case, you ...
  • identify the branches of the circuit
  • associate a current variable with each branch
  • identify each node of the circuit (place where 2 or more branches meet)
  • associate a voltage variable with each node
  • write the equation for each branch current in terms of the voltages at the nodes it is connected between
  • write the equation summing the currents into each node, recognizing that the sum of the currents into the node is zero.
  • solve the set of equations you have written.
You now have the solution to the circuit.
