| 1) The sum of two numbers is 12, and their difference is 2. What are the two numbers
Answer: 2 SOLUTION 1 : The sum of two numbers is 12. Their difference is 2. What are the two numbers Think of pairs of numbers whose difference is 2. Then find the sum of each pair. 5 + 7 = 12 5 - 7 = 2 The numbers are 7 and 5.

| 2) The difference of two numbers is 2, and their sum is 8. What are the two numbers
Answer: 2 SOLUTION 1 : Think of pairs of numbers whose difference is 2. Then find the sum of each pair. 5- 3 = 2 5 = 3 = 8 The numbers are 5 and 3. |
| 3) The difference of two numbers is 4. The sum of the two numbers is 20. What are the two numbers
Answer: 1 SOLUTION 1 : Think of pairs of numbers whose difference is 4. Then find the sum of each pair. 12 - 8 = 4 12 + 8 = 20 The numbers are 12 and 8. |
| 4) The sum of two numbers is 9, and their difference is 1. What are the two numbers
Answer: 2 SOLUTION 1 : Think of pairs of numbers whose difference is 1. Then find the sum of each pair. 5 - 4 = 1 5 + 4 = 9 The numbers are 5 and 4. |
| 5) The sum of two numbers is 22, and their difference is 2. What are the two numbers
Answer: 2 SOLUTION 1 : Think of pairs of numbers whose difference is 2. Then find the sum of each pair. 12 - 10 = 2 12 + 10 = 12 The numbers are 12 and 10.

| 6) The sum of two numbers is 21. The difference of the two numbers is 1. What are the two numbers
Answer: 4 SOLUTION 1 : Think of pairs of numbers whose difference is 1. Then find the sum of each pair. 11 - 10 = 1 11 + 10 = 21 The numbers are 11 and 10. |
| 7) The difference of two numbers is 3, and their sum is 15. What are the two numbers
Answer: 1 SOLUTION 1 : Think of pairs of numbers whose difference is 3. Then find the sum of each pair. 9 - 6 = 3 9 + 6 = 15 The numbers are 9 and 6. |
| 8) The difference of two numbers is 6. Their sum is 18. What are the two numbers
Answer: 3 SOLUTION 1 : Think of pairs of numbers whose difference is 6. Then find the sum of each pair. 12 - 6 = 6 12 + 6 = 18 The numbers are 12 and 6. |
| 9) The difference of two numbers is 8. Their sum is 16. What are the two numbers
Answer: 4 SOLUTION 1 : Think of pairs of numbers whose difference is 8. Then find the sum of each pair. 12 - 4 = 8 12 + 4 = 16 The numbers are 12 and 4. |
| 10) The difference of two numbers is 5. The sum of the two numbers is 13. What are the two numbers
Answer: 1 SOLUTION 1 : Think of pairs of numbers whose difference is 5. Then find the sum of each pair. 9 - 4 = 5 9 + 4 = 13 The numbers are 9 and 4. |
