They write: 2x - 6 = 5x + 1 → -3x = 7 → x = -7/3 Matematika Feladatgyujtemeny 9-10 Megoldasok

→ Focus revision on topics marked ❌. A solution key is a learning tool , not a shortcut. Every time you look up an answer, you lose a chance to grow your problem-solving muscle. Best study method with this book: Solve → Check → Understand → Re-solve → Teach someone else. | Problem nr | Topic | Solved alone

Good luck with your matematika studies! If you have a specific problem type you're stuck on (e.g., quadratic inequalities or Thales' theorem), let me know and I’ll explain it step by step. Every time you look up an answer, you

2x - 6 = 5x + 1 -6 - 1 = 5x - 2x -7 = 3x → x = -7/3

→ You made a sign error: did you write -6 - 1 = -7 correctly? 6. Where to find the solutions | Source | Availability | |--------|--------------| | Back of the workbook | Usually only final answers , not full steps. | | Separate "Megoldások" book (blue cover often) | Full step-by-step solutions. | | Teacher’s copy | Ask politely to borrow or photocopy a section. | | Online (PDF) | Some Hungarian educational sites offer partial solutions. Be careful – many are unofficial and contain errors. | | Study groups | Share and compare solutions with classmates. | 7. Advanced tip: Use the answer key to find your weak topics Make a table:

Same result – good. But note they grouped terms differently ( -3x = 7 vs -7 = 3x ). Both fine.
