Question

решите уравнение
72 : х = 8
9х = 81

12х = 24 + 24
8х =72 - 16

24 : х = 12 - 8
66 = 66 : х

помогите пожалуйста

Answer 1

Ответ:

1) 72 : x = 8

x = 72 : 8

x = 9

2) 9x=81

x = 81 : 9

x = 9

3) 12x=24+24

12x = 48

x = 48:12

x = 4

4)8x = 72-16

8x = 56

x = 56:8

x = 7

5) 24:x=12-8

24:x=4

x = 24 : 4

x = 6

6)66=66:x

x= 66 : 66

x = 1

Answer 2

72 : х = 8

х=72:8

х=9

9х = 81

х=81:9

х=9

12х = 24 + 24

12х= 48

х=48: 12

х= 4

8х =72 - 16

8х= 56

х= 56: 8

х=7

24 : х = 12 - 8

24 : х=4

х= 24:4

х=6

66 = 66 : х

66:66 = х

1=х

х=1
