a : b = 3 r 16 = > a = 3b + 16 = > a = 3 * 2c + 16 = > a = 6c + 16
b : c = 2 = > b = 2c
a + b + c = 459
Inlocuim in a treia relatie :
6c + 16 + 2c + c = 459
9c + 16 = 459 = > 9c = 459 - 16 = > 9c = 443 = > c = 443 : 9 = > c = 49, 2
Acum afla celelalte doua puncte :
a = 6 * 49, 2 + 16 = > a = 295, 2
b = 2 * 49, 2 = > b = 98, 4
