The paper deals with a problem of asymptotic soliton-like solutions to the Benjamin-Bona-Mahony (BBM) equation with a small parameter at the highest derivative and variable coefficients depending on the variables x and t, as well as a small parameter. An algorithm for constructing solutions to the BBM equation has been proposed, and theorems on accuracy of such solutions have been proved.
