fie numerele: x;y si z
stiim ca: x=2y ; z=3y => x + y + z = 15042
2y + y +3y= 15042
6y = 15042
y = 2507
↓
x = 2×2507 = 5014
z = 3×2507 = 7521
Adaug si rezolvarea cu metoda grafica ...
y = |___|
x = |___|___|
z = |___|___|___|
x+y+z = 6×|___| = 15042 deci: |___| = 15042 : 6 = 2507 adica y = 2507
x = |___|___|=2507+2507=5014 deci x = 5014
z = |___|___|___|=3×2507=7527 deci z = 7421
