In this paper, we summarize the sufficient and necessary conditions of solutions for the distributive equation of implication I(x,T 1(y,z)) = T 2(I(x,y),I(x,z)) and characterize all solutions of the functional equations consisting of I(x,T 1(y,z)) = T 2(I(x,y),I(x,z)) and I(x,y) = I(N(y),N(x)), when T 1 is a continuous but not Archimedean triangular norm, T 2 is a continuous and Archimedean triangular norm, I is an unknown function, N is a strong negation. We also underline that our method can apply to the three other functional equations closely related to the above-mentioned functional equations.
