Classical equations of motion for three-dimensional sigma-models in curvedbackground are solved by a transformation that follows from the Poisson-LieT-plurality and transform them into the equations in the flat background.Transformations of coordinates that make the metric constant are found and usedfor solving the flat model. The Poisson-Lie transformation is explicitlyperformed by solving the PDE's for auxiliary functions and finding the relevanttransformation of coordinates in the Drinfel'd double. String conditions forthe solutions are preserved by the Poisson-Lie transformations. Therefore weare able to specify the type of sigma-model solutions that solve also equationsof motion of three dimensional relativistic strings in the curved backgrounds.Simple examples are given
