Abstract: Bounds on the norms of transformed relative errors of solutions to simultaneous linear algebraic equations (SLAEs) taking into account the influence of errors in the specification of the lefthand side matrix and the right-hand side vector for various types of regularization are obtained. These bounds are valid in a wide range of values of the initial data.

Key words: numerical solution of simultaneous linear algebraic equations, bounds on solution errors, ill-conditioned matrices, regularization.
