The paper deals with the dual fully fuzzy matrix equation A {directX} X {direct+} B = C {directX} X {direct+} D. The dual fuzzy matrix equation is converted to a crisp system of matrix equations according to arithmetic operations of fuzzy numbers. The fuzzy approximate solution of fuzzy matrix equation is obtained by solving the model which is made of three linear matrix equations. The existence condition of the nonnegative fuzzy solution is also discussed. A example is given to illustrate the proposed method.
