📝 Solutions

Part 1 - One-Step Equations:

1. x + 7 = 15 → x = 8

2. y - 9 = 12 → y = 21

3. 4z = 28 → z = 7

4. w ÷ 3 = 6 → w = 18

5. m + 14 = 25 → m = 11

Riddle Answer: A ROAMER (8-21-8-11-21-7-21)

Part 2 - Two-Step Equations:

6. 2x + 5 = 17 → 2x = 12 → x = 6

7. 3y - 8 = 13 → 3y = 21 → y = 7

8. 4z + 9 = 29 → 4z = 20 → z = 5

9. 6w - 15 = 21 → 6w = 36 → w = 6

Riddle Answer: IT HAD TOO MANY PROBLEMS (6-7 5-6-7 7-6-6 5-6-7-5 7-5-6-6-7-5-6-7)

Part 3 - Challenge Equations:

10. 5(x - 3) = 20 → 5x - 15 = 20 → 5x = 35 → x = 7

11. 2y + 7 = 3y - 5 → 7 + 5 = 3y - 2y → 12 = y → y = 12

12. Sample answers: x + 5 = 15, 2x = 20, x - 3 = 7, etc.
