Answer 1

Răspuns:

404, 606, 808

Explicație pas cu pas:

$x + y + z = 1818 \\ \frac{x}{2} - 100 = k = > x = 2k + 200\\ \frac{y}{2} - 200 = k + 1 = > y = 2k + 402 \\ \frac{z}{2} - 300 = k + 2 = > z = 2k + 604 \\ 2k + 200 + 2k + 402 + 2k + 604= 1818 \\ 6k + 1206 = 1818 \\ 6k = 612 \\ k = 102 \\ x = 2 \times 102 + 200 = 404 \\ y = 2 \times 102 + 402 = 606 \\ z = 2 \times 102 + 604 = 808$
