Question

suma a trei nr este 212. daca impartim al doilea numar la primul,obtinem 3si restul5,iar daca impartim al treilea numar la al doilea ,obtinem catul 2si restul7 aflati cele trei nr

Answer 1

a+b+c=212
b:a=3 rest 5=>b=3a+5
c:b=2 rest 7=>c=2b+7=>c=2*(3a+5)+7=>c=6a+17

a+3a+5+6a+17=212
10a+22=212
10a=212-22
10a=190
a=19

b=3*19+5
b=62

c=6*19+17
c=131
