На першому складі було в 3 рази більше телевізорів, ніж на другому. Коли з першого складу вивезли 20 телеві- зорів, а на другий привезли 14, телевізорів на обох скла- дах стало порівну. Скільки телевізорів було на кожному складі спочатку?

Відповідь:

Покрокове пояснення:

Нехай х-другий склад,тоді перший склад-3х.Маємо рівняння:

3х-20=х+14

3х-х=20+14

2х=34

х=17-на другому складі

Тоді на першому складі=3х=17*3=51т.Отже:

перший склад=51т.

другий склад=17т.
