Question

The sum of two consecutive odd numbers is 20 and their difference is 2. Find the two numbers​

Answer 1

9 and 11

Explanation:

let the consecutive odd numbers be n and n + 2, then

n + n + 2 = 20

2n + 2 = 20 ( subtract 2 from both sides )

2n = 18 ( divide both sides by 2 )

n = 9 and n + 2 = 9 + 2 = 11

The 2 numbers are 9 and 11
