1. Answer:

   The numbers are 3 and 6 .

   Step-by-step explanation:

   Let the first number be x and other be y.

   ATQ,

   x/y = 1/2

   y = 2x ——- eq 1

   x+4/ y+4 = 7/10

   10x – 7y = -12 ——– eq 2

   Put y = 2x in eq 2 ,

   10x – 7(2x) = -12

   10x -14 x = -12

   -4x = -12

   x = -12/ -4

   x = 3

   Put x = 3 in eq 1 ,

   y = 2 (3)

   y= 6

   Therefore, the numbers are 3 and 6 .
