Bonsoir

x + 9,2 = 15

x + 9,2 - 9,2 = 15 - 9,2

x = 5,8

x - 9,6 = 3,8

x - 9,6 + 9,6 = 3,8 + 9,6

x = 13,4

3x = 7,2

3x/3 = 7,2/3

x = 2,4

-3x = -15,09

-3x/-3 = -15,09/-3

x = 5,03

2x + 3 = 45

2x + 3 - 3 = 45 - 3

2x = 42

2x/2 = 42/2

x = 21

5x - 6 = 18

5x - 6 + 6 = 18 + 6

5x = 24

5x/5 = 24/5

x = 4,8

8x - 6 = 5x + 12

8x - 6 + 6 = 5x + 12 + 6

8x - 5x = 5x + 18 - 5x

3x = 18

3x/3 = 18/3

x = 6

7x + 2 = -47

7x = -47 - 2

x = -49/7

x = -7
