→ You made a sign error: did you write -6 - 1 = -7 correctly? 6.

2x - 6 = 5x + 1 -6 - 1 = 5x - 2x -7 = 3x → x = -7/3 → You made a sign error: did you

Same result – good. But note they grouped terms differently ( -3x = 7 vs -7 = 3x ). Both fine. | | Separate "Megoldások" book (blue cover often)

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

→ 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.

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.
