Similar questions were asked and answered a lot. You deal with a nonlinear system with 7 parameters. Because Maple cannot solve it, the empty output is produced by the solve command. After evaluating the parameters, the system under consideration can be solved numerically.

>eq5:= (((Nd)^((epsilon-1)/epsilon)+Fu^((epsilon-1)/epsilon))^(1/(1-epsilon)))*(Fu)^(-1/epsilon)=(lamu/Lamd)*(1-((2*theta*(Fd-Fu))/lamu)):

>eq6:= (((Nd)^((epsilon-1)/epsilon)+Fu^((epsilon-1)/epsilon))^(1/(1-epsilon)))*(Nd)^(-1/epsilon)=(lamd/Lamd):
> fsolve(eval({eq5, eq6}, [epsilon = 2, lamu = 5, Lambd = 7.3, theta = 1, lamd = 4, Lamd = 7.1, Fd = 4.1]));

{Fu = 2.546355314, Nd = 0.5701215582}
