Salut,

Explications étape par étape

a. 2x – 3 = 0

x=3/2

x=1,5

b. 7x + 5 = 0

x = -5/7

x=-0.71

C. 5 + 4x = 0

4x = -5

x = -5/4

x=-1.25

D. 7x-8 = 0

7x=8

x=8/7

X=1,14

E. -3x + 5 = 0

-3x = -5

X=5/3

F. -2x- 9 = 0

-2x = 9

=-9/2

=-4,5

G. -1 -5x = 0

-5x = 1

=-1/5

=-0,2

H. 6x = 0

=6=0

X=0
