Bonjour pourriez vous m'aidez svp à faire ces inéquations en détaillant les calculs merci. ​

Bonjour

a. 2x - 1 = 52x + 1

2x - 52x = 1 + 1

- 51x = 2

x = - 2/51

b. 5x + 3 - 2x - 1 = x - 1 + 3x + 2

5x - 2x - x - 3x = - 1 + 2 - 3 + 1

- x = - 1

x = 1

c. 4/3x - 5 = 2x + 3

1/3x - 2x = 3 + 5

1/3x - 6/3x = 8

- 5/3x = 24/3

- 5x = 24

x = - 24/5

d. 3x + 5 - 8 = 3x + 2x + 1

3x - 3x - 2x = 1 - 5 + 8

- 2x = 4

x = - 4/2

x = - 2.

e. 3/5x + 2/3 = 2/5x + 10/3

3/5x - 2/5x = 10/3 - 2/3

1/5x = 8/3

3x = 40

x = 40/3

f. 3 (1/3x + 2) = 6x + 3 - 7x + 4

3/3x + 6 = 6x + 3 - 7x + 4

x - 6x + 7x = 3 + 4 - 9

0x = - 5
