The sum of 3 consecutive integers is greater than 30.

Let the first consecutive integer be n
The second consecutive integer is n + 1
The third consecutive integer is n + 2

The sum is written as:
n + n + 1 + n + 2

Combine like terms:
(n + n + n) + (1 + 2)
3n + 3

The phrase greater than means an inequality, which we write as:
3n + 3 > 30
