Решите уравнение: 1) 100 : (18 + (82-10 х) : 6) = 52) (105 - (25 + 6 х) * 4) * 30=150

1) 100 : (18 + (82 - 10 х) : 6) = 5.

100 : (18 + 82/6 - 10/6 х) = 5,

18 + 82/6 - 10/6 х = 100 : 5,

- 5/3 х = 20 - 18 - 41/3,

- 5/3 х = 2 - 41/3,

- 5/3 х = (2 * 3) / 3 - 41/3,

- 5/3 х = 6/3 - 41/3,

- 5/3 х = (6 - 41) / 3,

- 5/3 х = - 35/3,

х = 35/3 : 5/3,

х = 35/3 * 3/5 = 35 : 5 = 7,

Ответ: х = 7.

2) (105 - (25 + 6 х) * 4) * 30 = 150.

105 - (25 * 4 + 4 * 6x) = 150 : 30,

105 - 100 - 24 х = 5,

5 - 24 х = 5,

24 х = 5 - 5,

24 х = 0,

х = 0,

Ответ: х = 0.
