1107. Решите уравнение: 1) (327x - 5295) : 57 = 389; 2) (27x+11) · 315 = 11 970.

Решим уравнение:

1. (327x - 5295) : 57 = 389

   $$327x - 5295 = 389 \cdot 57$$

   $$327x - 5295 = 22173$$

   $$327x = 22173 + 5295$$

   $$327x = 27468$$

   $$x = 27468:327$$

   $$x = 84$$

2. (27x+11) · 315 = 11 970

   $$27x + 11 = 11970:315$$

   $$27x + 11 = 38$$

   $$27x = 38 - 11$$

   $$27x = 27$$

   $$x = 27:27$$

   $$x = 1$$

Ответ: 1) x = 84; 2) x = 1
