Answer 1

a+a+2+a+4 = 66
3a=66-6
3a=60
a=60:3
a=20
b=22
c=24

Answer 2

Metoda figurativa :

Notam numerele cu a, b si c :

a |--------|
b |--------|-2-|         } 66
c |--------|-2-|-2-|

2 + 2 + 2 = 6
66 - 6 = 60

Observam ca sunt 3 segmente :

60 : 3 = 20 ( a )
b = 20 + 2 => b = 22
c = 20 + 2 + 2 => c = 24

verificam : 20 + 22 + 24 = 66
