1. Answer:

   the 2 no.s are 4 and 11

   Step-by-step explanation:

   let x and y be the 2 no.s

   given, that x+y = 15 and x-y=7

   consider, (x+y) + (x-y)

   => (x+y) + (x-y) = 15+7

   => 2x = 22

   => x = 22/2

   => x = 11

   so, substitute x=11 in x+y=15

   => 11+y = 15

   => y = 15-11

   => y = 4

   so, the 2 no.s are 4 and 11

2. Answer:

   The numbers are 4 and 11

   Step-by-step explanation:

   let x and y be the 2 no.s

   given, that x+y = 15 and x-y=7

   consider, (x+y) + (x-y)

   = (x+y) + (x-y) = 15+7

   = 2x = 22

   = x = 22/2

   = x = 11

   on substituting x=11 in x+y=15, we get

   =11+y = 15

   = y = 15-11

   = y = 4

   ∴The 2 no.s are 4 and 11
