Question

a+b+c=56. daca impartim primul nr la al doilea obtinem 2 rest 7,iar daca impartim pe al doilea la al treilea obtinem 3 rest 3.determinati cele trei numere

Answer 1

a+b+c=56
a:b=2 rest 7 => a=2b+7
b:c=3 rest 3 => b=3c+3

a=2b+7=>a=2*(3c+3)+7=>a=6c+6+7=>a=6c+13

6c+13+3c+3+c=56
10c+16=56
10c=40
c=4

b=3*4+3
b=15

a=6*4+13
a=37
