Hint:

Replace the voltage source with a DC 1 Ampere current source with its positive direction upwards as in the figure. Connect the bottom nodes to ground. Assign voltage voltages to three nodes on top such as V1, V2 and V3. Perform nodal analysis and you will get three linear equations. Use Kramer's rule or Gauss jordan method to get the voltages V1,V2 and V3. The voltage V1 on the positive terminal of 1A current source would give you equivalent resistance of the circuit. \$R_{eq}= \frac {V_{1}}{1}\$.
