Question

suma a doua numere este 245.impartind numarulmai mare la diferenta celor doua nunere se obtine catul 4 si restul 7.aflati numerele

Answer 1

a+b=245=>b=245–a
a:(a–b)=4 rest 5
D=I×C+R; R≤I;
a=(a–b)×4+5
a=(a–245–a)×4+5
a=(-245)×4+5
a=–980+5
a=–975
a+b=245
–975+b=245
b=245+975
b=1220
Verificare: –975+1220=245
