a+b+c=460 a:b=1 rest c⇒a= bx1+c c=b-80⇒b=c+80 _______________ a=|__|+80+c b=|__|+80 c=|__| 460-160=300 300:3=30(numarul c) 80+30=110(numarul b) 110+80+30=190+30 =220(numarul a) mi se pare ca am gresit undeva :|
a+b+c= 460
a:b=1,c ---> a= 1x b +c --> a=b+c ; a= c+80+c=2c+80
c=b - 80 --> b=c+80
a + b + c=460
↓ ↓ ↓
2c+80+ c+80+ c=460
2c+c+c +160 =460
4c+160=460 ---> 4c=460 - 160= 300
c=300 : 4=75
b=75+80=155
a=2x75 + 80=150+80=230
a=230 ; b=155 ; c=75
