A*b=24
(a+1)*b=28...Deci a*b+b=28...24+b=28....b=4...a=6
Cu placere! Bafta!
cum ai gasit pe 6 si 4
:)...Pai...am scris cum am gasit... Inlocuiesti in ecuatia a*b+b=28 a*b=24...si obtinem 24+b=28..de unde rezulta b=28-24=4... Apoi inlocuiesti pe b=4 in ecuatia a*b=24...deci a =6

A*b=24→b=24/a.... (a+1)*b=28→24/a * (a+1)= (24a+24)/a=28 →24a+24=28a.... 4a=24=> a=6 ____ ab=24.... 6b=24 => b=4
