Algorithms are proposed for computing the characteristic polynomial, determinant, and adjoint matrix for a n \times n matrix and for solving a system of n-1 linear homogeneous equations in n variables by Cramer's rule using O(n^{4}) ring operations (without the division operation) over an arbitrary commutative ring. The exponent in the estimate of the computation time can be additionally reduced if an algorithm of asymptotically fast matrix multiplication is used.
