Please help me with this question!

Consider a two-player game (N; X; SA, SB; (UA, UB)), where N = {A, B} is the set of players, SA = {SA, SA, S'A}, SB = {SB; SB, SB, SB) are the sets of strategies of players respectively, and uA : SA X SB - R is the payoff function of the player A, which is given by UASA, SB) = 6; UA (SA, SB) = 6; UA (SA, SB) = B; UA (SA, SB) = S; UA (SA, SB) = 6; UA (SA, SB) = 7; UA (SA, s;) = a; UA (SA, sb) = =; UA (SA, SB) = 6; UA (SA , SB) = 6; UA (SA, SB) = Q; UA (SA, SB) = E, while uB : SA X SB - R is the payoff function of the player B, which is given by UB (SA, SB) = 7; UB (SA, SB) = 6 UB (SA, SB) = 7; UB (SA, SB) = 7; UB (SA, SB) = (; UB (SA, SB) = 6; UB (SA, SB) = 7; UB (SA, SB) = &; UB (SA, SB) = B; UB (SA, SB) = 7; UB (SA, SB) = B; UB (SA, SB) = Q, where note that a, 3, 7, 6, 6, E, ( are real numbers satisfying a
