Answer: 26 and 39

Explanation:

Let the numbers be x and y . Also , let us take x as the larger number.

From the first statement :

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

From the second statement :

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

Solving the system of linear equation by elimination method. Let us eliminate y first , then we need to add the two equations to eliminate y , the equation then becomes

2x = 78

x =39

substitute x = 39 into equation 1 , that is

39 + y = 65

y = 65 - 39

y = 26

Therefore , the numbers are 26 and 39
