# Choose the equation that could be used to find two consecutive integers whose sum is 69.

n + (n + 2) = 69

n + (n + 1) = 69

n - (n + 1) = 69

n + 2n = 69

**Solution:**

Consider the first number as n

As they are consecutive integers we know that the second number is n + 1

n + (n + 1) = 69

By further calculation

n + n + 1 = 69

2n + 1 = 69

2n = 69 - 1

2n = 68

Dividing both sides by 2

n = 34

First number n = 34

Second number n + 1 = 35

Therefore, the equation is n + (n + 1) = 69.

## Choose the equation that could be used to find two consecutive integers whose sum is 69.

**Summary:**

The equation that could be used to find two consecutive integers whose sum is 69 is n + (n + 1) = 69.
