240. Решите уравнение: 1) \(10x - 4x = 2,226\); 2) \(6x + 2x + 2,352 = 4,2\); 3) \(7x - 10,36 = 6,51\); 4) \(4,42 - 14x = 3,3\).

Решение уравнений: 1) \(10x - 4x = 2,226\) \(6x = 2,226\) \(x = \frac{2,226}{6}\) \(x = 0,371\) Ответ: \(x = 0,371\) 2) \(6x + 2x + 2,352 = 4,2\) \(8x = 4,2 - 2,352\) \(8x = 1,848\) \(x = \frac{1,848}{8}\) \(x = 0,231\) Ответ: \(x = 0,231\) 3) \(7x - 10,36 = 6,51\) \(7x = 6,51 + 10,36\) \(7x = 16,87\) \(x = \frac{16,87}{7}\) \(x = 2,41\) Ответ: \(x = 2,41\) 4) \(4,42 - 14x = 3,3\) \(-14x = 3,3 - 4,42\) \(-14x = -1,12\) \(x = \frac{-1,12}{-14}\) \(x = 0,08\) Ответ: \(x = 0,08\)
