2 + x = 6

x = 2

x = 4

a pour solution...

2 + x = 6

x = 4

a pour solution...

2 + x = 6

x = 6 - 2

x = 4

Solution

-2 + x = 4

x = 6

x = 2

a pour solution...

-2 + x = 4

x = 6

a pour solution...

-2 + x = 4

x = 4 + 2

x = 6

Solution

x + 3 = -6

x = 3

x = -9

a pour solution...

x + 3 = -6

x = -9

a pour solution...

x + 3 = -6

x = -6 - 3

x = -9

Solution

-4 + x = -16

x = 4

x = -12

a pour solution...

-4 + x = -16

x = -12

a pour solution...

-4 + x = -16

x = -16 + 4

x = -12

Solution

12 = x + 6

x = 6

x = 2

a pour solution...

12 = x + 6

x = 6

a pour solution...

12 = x + 6

ou

x + 6 = 12

x = 12 - 6

x = 6

Solution

20 = -5 + x

x = 15

x = 25

a pour solution...

20 = -5 + x

x = 25

a pour solution...

20 = -5 + x

ou

-5 + x = 20

x = 20 + 5

x = 25

Solution

-8 = -4 + x

x = 12

x = -4

a pour solution...

-8 = -4 + x

x = -4

a pour solution...

-8 = -4 + x

ou

-4 + x = -8

x = -8 + 4

x = -4

Solution

-25 = x + 5

x = -30

x = 20

a pour solution...

-25 = x + 5

x = -30

a pour solution...

-25 = x + 5

ou

x + 5 = -25

x = -25 - 5

x = -30

Solution

10 + x = 2

x = -8

x = 5

a pour solution...

10 + x = 2

x = -8

a pour solution...

10 + x = 2

x = 2 - 10

x = -8

Solution

8 + x = -4

x = 4

x = -12

a pour solution...

8 + x = -4

x = -12

a pour solution...

8 + x = -4

x = -4 - 8

x = -12
