Find 2 consecutive integers with

a sum of 15

Setup relational equation

We need to find 2 integers, n and n + 1, who have a sum = 15
n + (n + 1) = 15

Grouping like terms, we get 2n + 1 = 15

Subtract 1 from each side:

Cancel the ±1 from each side and simplify:

2n + 1 - 1 = 15 - 1

2n = 14

Divide each side by 2:

2n
=
14
2

Cancel the 2's on the left side of the equation and simplify:

2n
2
=
  
14
2

First Answer:

n = 7

Determine the 2nd Integer:

Now, since we found our first integer, our 2nd integer is just one greater:

(n + 1) = 7 + 1

Second Answer:

(n + 1) = 8

Final Answers:

n = 7
(n + 1) = 8
