Question

Impartind pa a la b,se obtine catul 1 si restul c.Suma nr a,b,c edte 94, iar b edte cu 9 mai mare decat c.Aflati nr?

Answer 1

a:b=1rc => a=b+c => a=2c+9
a+b+c=94
b=c+9

2c+9+c+9+c=94
4c=76 => c=19
a=47
b=28

Answer 2

a : b = 1 ; rest = c =>
b = c+ 9
a = b + c adica a = 2c + 9
a + b + c = 94 deci
2c + 9 + c + 9 + c = 94
4c + 18 = 94
4c = 76
c = 19
a = 2c + 9
a = 2 • 19 + 9
a =38 + 9
a = 47
b = c + 9
b = 19 + 9
b = 28
