This paper analyzes the system of equations by using the block ABS algorithm that righthand side is the fuzzy vector and the coefficient matrix is the crisp matrix. The fuzzy linear system (FLS) is converted to the extended crisp system and then the block ABS method is used for solving this system. We use the special case of block ABS algorithm and consider some properties of this system when the coefficient matrix is an M -matrix,
