équations
1) 3a +6 =9
2) 4B - 7=2
3) -2c + 5=9
4) 5d =10
5) 6e-9=-2
6)2f + 8 = f + 12
7) 3h = 6h - 9
8)8g - 16 = 4g
9)-3j + 5 = j+ 3
10) -4k - 2 =-2k + 6

Merci :)

Bonjour

Résoudre les  équations

1) 3a +6 =9

3a = 9 - 6

3a = 3

a = 3/3

a = 1

2) 4B - 7=2

4B = 2 + 7

4B = 9

B = 9/4

3) -2c + 5=9

- 2c = 9 - 5

- 2c = 4

c = - 4/2

c = - 2

4) 5d =10

d = 10/5

d = 2

5) 6e-9= -2

6e= - 2 + 9

6e = 7

e = 7/6

6)2f + 8 = f + 12

2f - f = 12 - 8

f = 4

7) 3h = 6h - 9

3h - 6h = 9

- 3h = 9

h = - 9/3

h = - 3

8)8g - 16 = 4g

8g - 4g = 16

4g = 16

g = 16/4

g = 4

9)-3j + 5 = j+ 3

- 3j - j = 3 - 5

- 4j = - 2

j = 2/4

j = 1/2

10) -4k - 2 =-2k + 6

- 4k + 2k = 6 + 2

- 2k = 8

k = - 8/2

k = - 4.
