Question

The sum of two consecutive odd integers is 80? What is the smaller number?​

Answer 1

39 , 41

Explanation:

Let the two consecutive odd numbers be (2x - 3) and (2x- 1)

2x - 1 + 2x -3 = 80

4x - 4 = 80

4x = 80 + 4

4x = 84

x = 84/4

x = 21

2x - 3 = 2*21 - 3 = 42-3 = 39

2x-1 = 2*21 - 1 = 42-1 = 41
