Question

scrieti nr 26 ca suma a doua nr naturale pare consecutive urgent dau coroana

Answer 1

I nr = a

II nr = a +2

a + a + 2 =26

2a + 2 = 26

2a = 26 - 2

2a = 24

a = 24 : 2

a = 12

I nr= 12

II nr = 12 + 2 = 14

Answer 2

Fie numerele a si b cu proprietatea b = a + 2

a + b = 26

a + (a + 2) = 26

2a = 26 - 2

a = 12

b = 12 + 2

b = 14
