The sum of two numbers is -2 and their difference is 8. What are the two numbers?

  1. 4 and 6

  2. -3 and 5

  3. -4 and -6

  4. 3 and -5

The correct answer is: -4 and -6

The sum of A is 10, B is 2, and D is -2, which do not meet the given sum of -2. While the difference of A is -2, B is -8, and D is 8, which do not meet the given difference of 8. Therefore, the only pair of numbers that meet both criteria is -4 and -6, making choice C the correct answer.
