-6x+2=9, -5x-15=3, -12+8x=1, -4-3x=6, -5x-3+7x=2, 2+6x-4=3. Svp détailler bien ne sauter pas d étape et celui qui me répond a ces équation vraiment je lui dit merci et pour info ce sont des équations

Sagot :

Bonjour,

-6x + 2 = 9

-6x = 9 - 2

-6x = 7

x = -7/6

- 5x - 15 = 3

- 5x = 3 + 15

- 5x = 18

x = -18/5

-12 + 8x = 1

8x = 1 + 12

8x = 13

x = 13/8

- 4 - 3x = 6

- 3x = 6 + 4

- 3x = 10

x = -10/3

- 5x - 3 + 7x = 2

2x - 3 = 2

2x = 2 + 3

2x = 5

x = 5/2 = 2.5

2 + 6x - 4 = 3

6x - 2 = 3

6x = 3 + 2

6x = 5

x = 5/6

Hey,

-6x + 2 = 9

-6x = 9 - 2

-6x = 7

x= -7 / 6

-5x - 15 = 3

-5x = 3 + 15

-5x = 18

x = -18 / 5

-12 + 8x = 1

8x = 1 + 12

8x = 13

x = 13 / 8

- 4 - 3x = 6

-3x = 6 + 4

-3x = 10

x = -10 / 3

-5x - 3 + 7x = 2

-5x + 7x = 2 + 3

2x = 5

x = 5/2

2 + 6x - 4 = 3

6x = 3 - 2 + 4

6x = 5

x = 5 / 6

Bonne soirée
