Answer:
14.5 & 5.5
Explanation:
- Two numbers have a sum of 20 and a difference of 9. What are these two numbers?
x+y=20
x-y=9
we subtract 9 (the difference) from 20 and divide the result by 2 to find the smallest number
(20-9):2=5.5
we add the difference and find the largest number
5.5+9=14.5
------------------
check
14.5+5.5=20
14.5-5.5=9
