Quelqu’un peut me résoudre sa svp

Bonjour,

3)

x * 4 = 12

4x = 12

x = 12/4

x = 3

6 * x = 24

6x = 24

x = 24/6

x = 4

8 * x = 64

8x = 64

x = 64/8

x = 8

1 * x = 3

x = 3

4 * x = 36

4x = 36

x = 36/4

x = 9

x * 6 = 0

6x = 0

x = 0

7 * x = 5,6

7x = 5,6

x = 5,6/7

4 * x = 2,4

4x = 2,4

x = 2,4/4

x = 0,6

8 * x = 30

8x = 30

x = 30/8

x = 15/4

4 * x = 30

4x = 30

x = 30/4

x = 15/2

4)

x + 14 = 102

x = 102 - 14

x = 88

6 * x = 162

6x = 162

x = 162/6

x = 27

8 * x = 264

8x = 264

x = 264/8

x = 33

98 + x = 315

x = 315 - 98

x = 217

x - 58 = 36

x = 36 + 58

x = 94.
