Решим уравнения:

1) x * 7 = 14 525 * 4

x * 7 = 58 100

x = 58 100 : 7

x = 8300

2) y * 9 = 54 324 : 6

y * 9 = 9054

y = 9054 : 9

y = 1006

3) z * 3 = 6030 * 5

z * 3 = 30150

z = 30150 : 3

z = 10050

4) u * 9 = 90 652 – 83 407

u * 9 = 7245

u = 7245 : 9

u = 805

5) v * 6 = 76 620 + 47 580

v * 6 = 124 200

v = 124 200 : 6

v = 20700

6) w * 4 = 100 000 – 91 720

w * 4 = 8280

w = 8280 : 4

w = 2070

Ответ: x = 8300; y = 1006; z = 10050; u = 805; v = 20700; w = 2070.
