Question

Un nr. nat. este cu 27 mai mare decat altul. Impartind suma lor la diferenta, se obtine catul 46 si restul 25. Aflati numerele. Pls help:)))

Answer 1

a=b+27
(a+b):(a-b)=46, rest 25 =>a+b=46(a-b)+25 =>46a-46b+25=a+b

46(b+27)-46b+25=b+27+b
46b+1242-46b+25=27+2b
1267-27=2b
1240=2b =>b=620
a=620+27 =>a=647

Answer 2

a=b+27
a+b:a-b=46r25
a+b=46(a-b)+25=>a+b=46a-46b+25
b+27+b=46(b+27)-46b+25
b+27+b=46b+1242-46b+25
2b=1242+25-27
2b=1240=>b=1240:2=>b=620
a=620+27
a=647
