3(2x + 4) = 6

x = 2

x = -1

a pour solution...

3(2x + 4) = 6

x = -1

a pour solution...

3(2x + 4) = 66x +12 = 66x = 6 - 126x = -6x = 6/-6x = -1

Solution

2(-2x + 5) = 8

x = -1

x = 0.5

a pour solution...

2(-2x + 5) = 8

x = 0.5

a pour solution...

2(-2x + 5) = 8-4x + 10 = 8-4x = 8 - 10-4x = -2x = -2/-4x = 0.5

Solution

6(4x + 2) = -6

x = 3

x = -0.75

a pour solution...

6(4x + 2) = -6

x = -0.75

a pour solution...

6(4x + 2) = -624x + 12 = -624x = -6 - 1224x = -18x = -18/24x = -3/4 = -0.75

Solution

-4(2x - 6) = -6

x = 3.75

x = 5

a pour solution...

-4(2x - 6) = -6

x = 3.75

a pour solution...

-8x + 24 = -6-8x = -6 - 24-8x = -30x = -30/-8x = 3.75

Solution

12 = 6(2x + 4)

x = -1

x = 4

a pour solution...

12 = 6(2x + 4)

x = -1

a pour solution...

12 = 12x + 2412x = 12 - 2412x = -12x = -12/12x = -1

Solution

20 = -5(x + 5)

x = -3

x = -9

a pour solution...

20 = -5(x + 5)

x = -9

a pour solution...

20 = -5x - 25-5x = 20 + 25-5x = 45x = 45/-5x = -9

Solution

-8 = -5(x + 2)

x = -0.4

x = 4

a pour solution...

-8 = -5(x + 2)

x = -0.4

a pour solution...

-8 = -5x - 10-5x = 10 - 8-5x = 2x = 2/-5x = -0.4

Solution

-25 = 2(5x - 5)

x = 6

x = -1.5

a pour solution...

-25 = 2(5x - 5)

x = -1.5

a pour solution...

-25 = 10x - 1010x = -25 + 1010x = -15x = -15/10x = -1.5

Solution

-5(2x + 2) = 2

x = -1.2

x = 1

a pour solution...

-5(2x + 2) = 2

x = -1.2

a pour solution...

-10x - 10 = 2-10x = 2 + 10-10x = 12x = -12/10x = -1.2

Solution

4(x - 2) = -4

x = -0,5

x = 1

a pour solution...

4(x - 2) = -4

x = 1

a pour solution...

4x - 8 = -44x = -4 + 84x = 4x = 4 : 4x = 1
