Pourriez vous m’aider à résoudre ces équations svp

3x = 4

x = 4/3

5x + 2 = 8

5x = 8 - 2

x = 6/5

4x + 8 = 3

4x = 3 - 8

x = -5/4

7x + 16 =0

7x = - 16

x = -16/7

bonjour

3 x = 4

  x = 4/3

5 x + 2 = 8

5 x = 8 -  2

5 x = 6

x = 6/5

4 x + 8 = 3

4 x = 3 - 8

4 x = - 5

x = - 5/4

7 x + 16 = 0

7 x = - 16

x = - 16/7
