2. Реши уравнения: 265 − y = 540 : 9; x + 91 = 1600 : 8; a · 45 = 150 · 3.

1. \(265 - y = 540 : 9\)

   \(265 - y = 60\)

   \(y = 265 - 60 = 205\)

2. \(x + 91 = 1600 : 8\)

   \(x + 91 = 200\)

   \(x = 200 - 91 = 109\)

3. \(a \cdot 45 = 150 \cdot 3\)

   \(a \cdot 45 = 450\)

   \(a = 450 : 45 = 10\)

Ответ: \(y = 205\), \(x = 109\), \(a = 10\).
