np.array([[4, 3, -5], [-2, -4, 5], [8, 8, 0]]) y = np.array([2, 5, -3]) x = np.linalg.solve(A, y) print(x) The result will be : [ 2.20833333 -2.58333333 -0.18333333] The solver is actually doing a LU decomposition to get the results. You can check the help of the function, it needs the input matrix
