Question

помогите люди добрые. даю 60 балов ​

Answer 1

Пошаговое объяснение:

4х = 24 + х

4х - х = 24

3х = 24

х = 24 : 3

х = 8

8х - 8 = 20 - 6х

8х + 6х = 20 + 8

14х = 28

х = 28 : 14

х = 2

4(х - 3) = х + 6

4х - 12 = х + 6

4х - х = 6 + 12

3х = 18

х = 18 : 3

х = 6

4 - 6(х + 2) = 3 - 5х

4 - 6х - 12 = 3 - 5х

-6х - 8 = 3 - 5х

-6х + 5х = 3 + 8

-х = 11

х = -11

Answer 2

Ответ:

1) 4х = 24+х

4х - х = 24

3х = 24

х = 24 : 3

х = 8

2) 8х - 8 = 20 - 6х

8х + 6х = 20 + 8

14х = 28

х = 28 : 14

х = 2

3) 4(х - 3) = х + 6

4х - 12 = х + 6

4х - х = 6 + 12

3х = 18

х = 18 : 3

х = 6

4) 4 - 6(х+2) = 3 - 5х

4 - 6х - 12 = 3 -5х

-6х + 5х = 3 - 4 + 12

-х = 11 : (-1)

х = - 11
