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
