Metoda algebrica
a+b+c=3851
b:a=3 rest 24 b=3a+24
c:a=6 rest 17 c=6a+17
inlocuim necunoscutele:
a+3a+24+6a+17=3851
10a+41=3851
10a=3810
a=381
b=3*381+24
b=1143+24
b=1167
c=6*381+17
c=2286+17
c=2303
proba: 381+1167+2303=3851
Metoda grafica:
a/___/
b/___/___/___/+24
c/___/___/___/___/___/___/+17 suma=3851
3851-24-17=3810
avem 10 segmente
3810:10=381
a=381
b=3x381+24
b=1143+24
b=1167
c=6x381+17
c=2286+17
c=2303
