reliez chaque equation a sa solution svp aidez moi ​

Bonjour

x + x + x = 10 - x

3x + x = 10

4x = 10

x = 10/4

x = 2,5

2x + 3 = 3x + 2

2x - 3x = 2 - 3

- x = - 1

x = 1

4 (1 - x) = 18

4 - 4x = 18

- 4x = 18 - 4

- 4x =  14

x = - 14/4

x = - 3,5

5x * 2 = 4x + 24

10x = 4x + 24

10x - 4x = 24

6x = 24

x = 24/6

x = 4.
