Question

un nr este cu 84 mai mare decat altul.Impartind suma celor doua nr la diferenta lor se obtine catul 15 si restul 14.Aflati cele 2 numere

Answer 1

a=b+84
(a+b):(a-b)=15 rest 14 =>a
a+b=15(a-b)+14
b+84+b=15(b+84-b)+14
2b+84=1260+14
2b=1274-84
2b=1190 =>b=595
a=595+84 =>a=679

Answer 2

a=b+84
(a+b):(a-b)=15r14
a+b=15(a-b)+14
a+b=15(b+84-b)+14=>a+b=1260+14=>a+b=1274
b+b+84=1274
2b=1274-84
b=1190:2=>b=595
a=595+84=>a=679
