Question

afla numerele a si b stiind ca daca leadunam obtinem 783, iar daca le impartim obtinem catu 7 si restul7 .( a mai mare ca b)

Answer 1

1. Facem egalizarea 783-7=776- reprezinta 8 parti egale. b = 776:8 =97 a=97*7+2=686

Answer 2

a+b=783
a:b=7 rest 7=> a=7b+7
7b+7+b=783
8b+7=783
8b=783-7
8b=776
b=776:8
b=97
a=7•97+7
a=686
inlocuim :
686+97=783
