The system of two-sided quaternion matrix equations with  η -Hermicity,  A  1  XA  1   η*   =  C  1 ,  A  2  XA  2   η*   =  C  2  is considered in the paper. Using noncommutative row-column determinants previously introduced by the author, determinantal representations (analogs of Cramer’s rule) of a general solution to the system are obtained. As special cases, Cramer’s rules for an  η -Hermitian solution when  C  1  =  C  η*  1  and  C  2  =  C  η*  2  and for an  η -skew-Hermitian solution when  C  1  = − C  η*  1  and  C  2  = − C  η*  2  are also explored.
