Răspuns :
a+b+b+c=10+16=26
a+c=24
26-24=2
2:2=1
b=1
16-1=15
c=15
10-1=9
a=9
a+c=24
26-24=2
2:2=1
b=1
16-1=15
c=15
10-1=9
a=9
(a + b) + ( a + c) + ( b + c) = 10 + 24 + 16
2 x a + 2 x b + 2 x c = 50
2 x ( a + b + c) = 50
a + b + c = 50 : 2
a + b + c = 25 → suma celor trei numere
25 - 16 = 9 → primul numar ( a)
10 - 9 = 1 ( b)
16 - 1 = 15 ( c)
2 x a + 2 x b + 2 x c = 50
2 x ( a + b + c) = 50
a + b + c = 50 : 2
a + b + c = 25 → suma celor trei numere
25 - 16 = 9 → primul numar ( a)
10 - 9 = 1 ( b)
16 - 1 = 15 ( c)
