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:
2n + 1 - 1 = 15 - 1Cancel 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:
| = |
| 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
(n + 1) = 8
What is the Answer?
n = 7
(n + 1) = 8
(n + 1) = 8
