Chiziqli tenglama

$ax + b = 0$ tenglama berilgan, bunda $a \ne 0$. Noma'lum $x$ ni toping.

Bitta qatorda ikkita butun son $a$ va $b$ ($1 \le |a|, |b| \le 1000$).

Bitta son — $x$, aniq 2 ta kasr xona bilan.

Tenglamadan $x = -\dfrac{b}{a}$. Ikki butun sonni bo'lishda C++ va Go kasr qismni tashlab yuborishini unutmang: 3 / 2 — 1. Bittasini haqiqiy songa aylantiring: -b / (double)a.
