Alyssa and Ben are trying to decide where to go to the football game or to the play. But Alyssa prefers the play and Ben the ball game, although they’d prefer to do somewhat together. The Nash equilibrium is: (w) Alyssa goes to the play and Ben to the ball game. (x) they both go to the ball game. (y) there is no Nash equilibrium. (z) Alyssa and Ben both go to the ball game OR both go to the play.

Can someone explain/help me with best solution about problem of Economics...
