Suma a doua numere naturale este 48.Aflati numerele,stiind ca, impartind unul dintre numere la celalalt,obtinem catul 3 si restul 4.

Answer 1

$a+b=48\\a:b=3 \ rest \ 4 \to \boxed{a=3b+4} \\********************\\3b+4+b=48\\4b+4=48\\4b=48-4\\4b=44\\b=44/4\\\boxed{b=11}\\ \\a+11=48\\a=48-11\\a=37$

Answer 2

a+b=48
a:b=3r4
a=3b+4
3b+4+b=48
4b=48-4
b=44:4
b=11
a=48-11=37
