Can I get some help on this question with answer and detailed explanation? I just have no idea how to approach and where to start...

Nash Equilibria For the following games, find all Nash equilibria in pure actions. [Hint: first perform IDSDA, then look for equilibria.] (a) P1.2 L R Pl. 1 T 3, 1 1,4 B 2,2 5,0 (b) P1.2 L C R T 2, 3 6. 3 2, 1 PI.1 M 3,2 1, 2 0, 0 B 2,0 0, 4 4, -1 (c) Blue L R Red T 0,0 2,3 B 4, 2 2, 2
