4. 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.

1) \(10x - 4x = 2.226\) \(6x = 2.226\) \(x = 2.226 / 6\) \(x = 0.371\) 2) \(6x + 2x + 2.352 = 4.2\) \(8x = 4.2 - 2.352\) \(8x = 1.848\) \(x = 1.848 / 8\) \(x = 0.231\) 3) \(7x - 10.36 = 6.51\) \(7x = 6.51 + 10.36\) \(7x = 16.87\) \(x = 16.87 / 7\) \(x = 2.41\) 4) \(4.42 - 14x = 3.3\) \(-14x = 3.3 - 4.42\) \(-14x = -1.12\) \(x = -1.12 / -14\) \(x = 0.08\)
