Безотлагательно!!! Помогите пожалуйста с уравнениями УМОЛЯЮ:х : 4 - 3 =

Ответ:

Пошаговое объяснение:

1.

x = 9*4 = 36

2.

x - 2 = = 9

x = 9+2 = 11

3.

x = 36:6 = 6

4.

x-5 = 63/7 = 9

x = 9+5 = 14

5.

x+15 = 432/24 = 216/12 = 108/6 = 54/3 = 18

x = 18-15 = 3

6.

3x - 15 = 252/14 = 126/7 = 18

3x = 18+15 = 33

x = 33/3 = 11

7.

112 - 5x = 816/8 = 102

-5x = 102-112 = -10

5x = 10

x = 10/5 = 2

8.

13x + 4x = 408

17x = 408

x = 408/17 = 24

9.

47x - 15x = 2144

32x = 2144

x = 2144/32 = 1072/16 = 536/8 = 268/4 = 134/2 = 67

10.

a + 23a = 1032

24a = 1032

a = 1032/24 = 516/12 = 258/6 = 129/3 = 43

11.

16x - x + 14 = 299

15x = 299-14 = 285

x = 285/15 = 57/3 = 19

12.

7b + 6b - 29 = 374

13b = 374 + 29 = 403

b = 403/13 = 31

13.

19y - 12y - 47 = 1388

7y = 1388+47 = 1435

y = 1435/7 = 205
