The sum of two integers is +5 and their difference is -21. Find the two numbers.

  • 1

Let the integers be x and y. Then x + y = 5 and x – y = -21. Adding both equations gives 2x = -16, so x = -8. Substituting yields y = 13. The numbers are -8 and 13.

1 Answer

  1. Let the two numbers be represented by x and y. From the given conditions, we form the pair of linear equations: x + y = 5 and x – y = -21. Adding these two equations eliminates y, resulting in 2x = -16, which gives x = -8. Substituting x = -8 into x + y = 5 gives -8 + y = 5, leading to y = 13. Thus, the two numbers are -8 and 13.
