№5. Решите уравнения 1) 2x - 7 + (6x + 1) = 18 2) (4 - 8.2x) - (3.8x + 1) = 5

1) 2x - 7 + (6x + 1) = 18

2x - 7 + 6x + 1 = 18

8x - 6 = 18

8x = 24

x = 3

2) (4 - 8.2x) - (3.8x + 1) = 5

4 - 8.2x - 3.8x - 1 = 5

3 - 12x = 5

-12x = 2

x = -$$ \frac{1}{6} $$

Ответ: 1) x = 3, 2) x = -$$ \frac{1}{6} $$
