Bonjour jai besoin d'aide merci.​

Réponse:

A) 4x - 12 = 0

A) 4x - 12 + 12 = 0 + 12

A) 4x = 12

A) x = 12/4

A) x = 3

B) 2x - 3 = 0

B) 2x - 3 + 3 = 0+ 3

B) 2x = 3

B) x = 1,5

C) 4x + 1 = 0

C) 4x + 1 - 1 = 0 - 1

C) 4x = -1

C) x = -0,25

D) 2-3x = 0

D) 2 - 3x - 2 = 0 - 2

D) -3x = -2

D) x = 2/3

-3 × 2/3 = -2

bonsoir :

4x - 12 = 0

4x = 12

× = 12/4

■x = 3 ■

4x + 1 = 0

4x = - 1

■x = -1/4■

2x - 3 = 0

2x = 3

■x = 3/2■

2 - 3x = 0

3x = 2

■× = 2/3■
