Bonjour

Explications étape par étape

4x = 16

4x/4 = 16/4

x = 4


5x = 10

5x/5 = 10/5

x = 2


3x = 9

3x/3 = 9/3

x = 3

Tu finis les deux dernières...

2x = 10


6x = 1



3x + 4 = 6

3x + 4 - 4 = 6 - 4

3x = 2

3x/3 = 2/3

x = 2/3


5x + 6 = 11

5x + 6 - 6 = 11 - 6

5x = 5

5x/5 = 5/5

x = 1


4x - 5 = 7

4x - 5 + 5 = 7 + 5

4x = 12

4x/4 = 12/4

x = 3


Tu finis...

6x + 1 = -5

3x - 5 = -2
