решить уравнения: 2x + 5x + 3,18 = 25,3; 8p - 2p - 14,21 = 75,1

Пошаговое решение:

Уравнение 1:

1. \[ 2x + 5x + 3.18 = 25.3 \]
2. \[ 7x + 3.18 = 25.3 \]
3. \[ 7x = 25.3 - 3.18 \]
4. \[ 7x = 22.12 \]
5. \[ x = 22.12 : 7 \]
6. \[ x \approx 3.16 \]

Уравнение 2:

1. \[ 8p - 2p - 14.21 = 75.1 \]
2. \[ 6p - 14.21 = 75.1 \]
3. \[ 6p = 75.1 + 14.21 \]
4. \[ 6p = 89.31 \]
5. \[ p = 89.31 : 6 \]
6. \[ p \approx 14.885 \]

Ответ: x ≈ 3.16; p ≈ 14.885
