The relativistic four-quark equations in the framework of the dispersion relation technique are derived. The four-quark amplitudes of the scalar tetraquarks with open bottom, including u, d, s and bottom quarks, are constructed. The poles of these amplitudes determine the masses and widths of scalar tetraquarks.
