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

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