Question

The sum of two consecutive integers is 5.

What are the numbers?
Hint. Consecutive integers differ by 1,
so let x = smaller integer and y = x + 1 =
next larger.

Answer 1

They are 2 and 3, since 2 + 3 = 5

Let x be the smaller number. Then

x + (x + 1) = 5

2x + 1 = 5

2x = 4

x = 2

x + 1 = 3
