7*c=250-9=241
c=241:7
c=34,......
cred ca problema e gresita (lol am gasit pana acum 3 probleme gresite :))

Answer 2

a+b+c=250
a:b=2 rest3⇒a=2b+3
b:c=2 rest 3⇒b=2c+3

a=2b+3
a=2(2c+3)+3⇒a=4c+6+3⇒a=4c+9

 a+b+c=250
4c+9+2c+3+c=250
7c+12=250⇒7c=250-12⇒7c=238⇒c=238:7⇒c=34

b=2c+3⇒b=2*34+3=68+3=71⇒b=71

a=2b+3⇒a=2*71+3=142+3=145⇒a=145

verificare:145+71+34=250    A
