Question

Write a pair of integer whose sum is 15 and difference is -9

Answer 1

Answer:

(12) and (3)

Step-by-step explanation:

Here, by trial and error method, we can firstly find out two numbers whose sum is 15 and difference is 9. Then we get 12 and 3.

But since, difference is (-9), then the numbers will 12 and 3 itself where 12 is subtracted from 3.

Verification :

12 + 3 = 15

3 - 12 = -9

Here (12) and (3) stands on the condition. Thus verified.
