Question

Find two consecutive intergers whose sum is 45

Answer 1

n + ( n+1 ) = 45

Step-by-step explenation:

2n+1=45

2n = 45 - 1

2n = 44

n = 44/2

n=22

22 and 23

Answer 2

The reqd. integers are

22 and 23

Explanation:

Since consecutive integers are required, we let them be

x and x + 1 . These add to 45

, we have, x + x + 1=45

⇒ 2x +1= 45

⇒2 x= 44

⇒ x= 22 and , s o x + 1 = 23
