: The core math syllabus hasn't changed significantly since 2013. If you can't find the 2013 PDF, search for OGE Lysenko 2020-2024 solutions; many of the "standard" algebraic problems and geometric theorems remain identical.
Finding a specific "GDZ" (ready-made homework solutions) for the older edition by Lysenko and Kulabukhov can be tricky, as most current online resources prioritize newer OGE (OGE replaced GIA) formats. spisat gdz po matematike 9 klass gia-2013 lysenko

: Detailed solutions for the more difficult "Part 2" problems (which require showing work) are often published in a separate companion book titled "Математика. 9 класс. Подготовка к ГИА-2013. Решебник" (Mathematics. 9th Grade. Preparation for GIA-2013. Solution Book).
