bonjours bonsoirs merci au personne qui son d'accord pour m'aider a faire ce devoirs merci

Bonsoir,

a) 6x = 36

x = 36/6

x = 6

b) 3x = 26

x = 26/3

x = 8.6

c) -4x = 39

x = - 39/4

x = - 9.75

d) 5x = -12

x = - 12/5

x = - 2.4

e) -12x = -52

x = -52/-12

x = 13/3

x = 4.3

f) x² = 144

x = racine de 144

x = 12

g) x² = 50

x = racine de 50

x = 7.07

i) x - 13 = 6

x = 6 + 13

x = 19

j) 7x + 1 = 15

7x = 15 - 1

7x = 14

x = 14/7

x = 2

k) 5x - 9 = 6

5x = 6 + 9

5x = 15

x = 15/5

x = 3

l) 2x + 5 = -7

2x = - 7 - 5

2x = - 12

x = -12/2

x = -6

m) - 3x - 2 = 19

-3x = 19 + 2

-3x = 21

x = 21/-3

x = -7

Voilà pour tes 12 équations, j'espère t'avoir aidé.

Ta note = 12/12
