VA ROGGGG URGENTTTTT DAU COROANAAAAAAAAAAAA

Answer 1

12. Fie a , b

a+b=256

a:b=6 rest 11 => a=6b+11

6b+11+b=256

7b+11=256 => 7b=256-11=245 => b=245/7=35 => a=6×35+11=221

13. Fie a

a:5=7 rest 1 (pentru a afla cea mai mica valoare a numarului a , s-a luat cea mai mica valoare a restului)

a=5×7+1=35+1=36

14. Fie a , b

a-b=139 => a=b+139

a:2b=10 rest 6 => a=20b+6

20b+6-b=139

19b+6=139 => 19b=139-6=133 => b=7 => a=7+139=146

15. Fie a , b

a+b=334

a:3b=36 rest 7 => a=3b×36+7=108b+7

108b+7+b=334

109b+7=334 => 109b=334-7=327 => b=327/109=3 => a=334-3=331

16. Fie a ,b , c

a+b+c=232

a:b=14 rest 5 => a=14b+5

b:c=7 rest 1 => b=7c+1 => a=14(7c+1)+5=98c+14+5=98c+19

98c+19+7c+1+c=232

106c+20=232 => 106c=232-20=212 => c=212/106=2 => b=7×2+1=15 => a=14×15+5=215
