Bonjour, pourriez vous m'aidez svp Résoudre les équations suivantes : 3x = 18 -5x = 48 84= 6x 5x+3= 45 -10x+68= 1

Bonjour,

Résoudre les équations suivantes :

3x = 18

x = 18/3

x = 6

-5x = 48

x = - 48/5

84= 6x

x = 84/6

x = 14

5x+3= 45

5x = 45 - 3

5x = 42

x = 42/5

-10x+68= 145

- 10x = 145 - 68

- 10x = 77

x = - 77/10

13x-45=112

13x = 112 + 45

13x = 157

x = 157/13

Bonjour,

3x = 18

x = 18/3 = 6

-5x = 48

x = -48/5 = -9.6

84 = 6x

x = 84/6 = 14

5x + 3 = 45

5x = 42

x = 42/5 = 8.4

-10x + 68 = 145

-10x = 145 - 68

-10x = 77

x = -77/10 = -7.7

13x - 45 = 112

13x = 112 + 45

13x = 157

x = 157/13
