First Number = x 

Second Number =y 

Case 1 

(x+2)/(y+2) = 1/2

Case 2 

(x-4)/(y-4) = 5/11

From 1 

2x - y = -2 ...... 3 

from 2 

11x - 5y = 24 .... 4 

Multiplying Eqn 1 by 5 

10 x - 5y = -10   .......5

Eqn 4 -Eqn 5 

11x - 5y -10 x + 5y = 24 + 10 

x = 34 

From Eqn 1 

2 (34) - y = -2 

or y = 68 + 2 = 70  Answer.
