Explications étape par étape :

a. 6+(3x-2)

=6+3x-2

=4+3x

b.-4x+(8-3x)

=-4x+8-3x

= -7x+8

c.10-(5-3x)

=10-5+3x

=5+3x

d.8x-(-3-5x)

=8x+3+5x

=13x+3

e. 5-(2x+3)x4

=5-(8x+12)

=5-8x-12

=-7-8x

f.2x-5(3x+4)

=2x-15x-20

=-13x-20

Bonjour,

Développer:

a. 6+3x-2= 3x+4

b. -4x+8-3x= -7x+8

c. 10-5+3x= 3x+5

d. 8x+3+5x= 13x+3

e. 5-(8x+12)= 5-8x-12= -8x-7

f. 2x-15x-20= -13x-20
