bonjour pouvez vous m'aider svp
Simplifier chaque expression autant que possible.
B = 9 - (4x - 1)
A = 9 x- (4x + 5)
C = 7x - 8 - (3 + 9x)
D = 11 - 6x - (2x - 10)
merci d avance ​

Bonjour !

B = 9 - (4x - 1)

B = 9 - 4x + 1

B = 10 - 4x

A = 9x - (4x + 5)

A = 9x - 4x - 5

A = 5x - 5

C = 7x - 8 - (3 + 9x)

C = 7x - 8 - 3 - 9x

C = -2x - 11

D = 11 - 6x - (2x - 10)

D = 11 - 6x - 2x + 10

D = 21 - 8x

J'espère t'avoir aidé. Bon courage !
