Question

Write down a pair of integeres
whose
Sum is - 9 difference is - 4​

Answer 1

Answer:

Step-by-step explanation:

Let the numbers be x and y

Given sum = -9

⇒ x+ y = -9                         ..............(1)

Given difference= -4

⇒ x - y = -4                          ..............(2)

On solving (1) &(2),

             x+ y = -9

          - (x - y = -4 )  

             2y= -5 ⇒ y = -2.5

   Substituting y in (1),  x + (-2.5) = -9 ⇒ x = -6.5

Hence the pair of integers are -2.5 & -6.5
