Question

Two consecutive intergers have a sum of 79, find the intergers

Answer 1

The integers are 39 and 40.

Explanation:

Let the smaller integer be x.

The next greater integer is x + 1.

Their sum is x + x + 1.

Their sum is 79, so

x + x + 1 = 79

Solve for x.

2x + 1 = 79

2x = 78

x = 39

x + 1 = 40
