Question

The sum of two numbers is 27. Their difference is 1. Find the smaller number.
​

Answer 1

Explanation:

Because the difference of the two numbers is 1, add 1 to 27 to get 28. Then, divide 28/2 to get the larger integer, 14. Then subtract one to get the other, 13.

Thus, the numbers are 13 and 14.

Hope it helps :D

Answer 2

13

Explanation:

We say a + b = 27 and and a - b = 1 where b is the smaller number.

a = 27 - b so (27 - b) - b = 1

2b = 26 so b = 13
