Answer: The two numbers are 39 and 26

Step-by-step explanation:

Let the numbers be x and y

From the information given,

x + y = 65...........equation 1

x - y = 13............equation 2

2x = 78

Divide both sides by 2

x = 78/2

x = 39

Insert the value of x into equation 1

39 + y = 65

Subtract 39 from from both sides

39 - 39 + y = 65 -39

y = 26

The two numbers are 39 and 26.
