Chiziqli tenglama yechish

A va B (A ≠ 0) sonlari berilgan. A·x + B = 0 chiziqli tenglamaning yechimi x ni toping.

func solve(A int, B int) float64 {
    // ...
}

Misollar

Input: A=2, B=6
Output: -3.0

Input: A=5, B=-10
Output: 2.0

Input: A=3, B=9
Output: -3.0

Maslahatlar

1. A·x + B = 0 tenglamadan A·x = −B.
2. x = −B / A. Bo'lishdan oldin sonlarni float64 ga aylantiring.
