Question

Daca impartim 2 numere, obtinem catul 3 si restul 10.Daca adunam cele doua numere, restul si catul, obtinem 143. Afla cele doua nunere.

Answer 1

$a:b=3r10 \\ a=3b+10 \\ a+b+3+10=143 \\ a+b=143-13 \\ a+b=130 \\ 3b+10+b=130 \\ 4b=130-10 \\ b=120:4 \\ b=30 \\ a=3*30+10 \\ a=100$

Answer 2

a:b=3  r=10
a+b+3+10=143
143-10-3 =130(a+b)
/--/b
/--/+10 a
130-10=120(suma imp. in 2 p. egale)
120:2=60 (b)
60+10=70 (a)
