3 * x1 = 2 * x2
5 * x2 = 4 * x3
11 * x3 = 6 * x4
x1 + x2 + x3 + x4 = 125
Выражаем: x2 = 1,5 * x1
x3 = 5 * x2 / 4 = 7,5 * x1 / 4 = 1,875 * x1
x4 = 11 * x3 / 6 = 11 * 1,875 * x1 / 6 = 3,4375 * x1
Итого: 125 = x1 + 1,5 * x1 + 1,875 * x1 + 3,4375 * x1 = 7,8125 * x1
x1 = 125 / 7,8125 = 16
x2 = 24
x3 = 30
x4 = 55
