A system of linear algebraic equations \(Ax= b\) is solved by the preconditioned conjugate gradient method. In each step it is usually necessary to solve an auxiliary system of linear equations. In the paper, instead of it, for preconditioning one iteration of the two level method for \(Ax= b\) is used.
