Let the numbers be x and y.
As per the question,
x+y =69
x-y = 17.
On equating both, you will get
x = 43
y= 26.

let the two numbers are x and y
now according to question:
    x+y=69
so     x= 69 -y   (eq: 1)
   and:
x-y=17   ( A.T.Q.)(equation - 2)
   now put value of x in equation - (2)
so, 69-y-y=17
     -2y=-52
      y= 26
now we have the value of y ..so put it in equation 1st
       x=69-y
       x=69-26    (y=26)
       x=43
so... two numbers whose sum is 69 and difference is 17 are:
   43 and 26
