bonsoir jai besoin daide pour cette exercice svp merci:
1) 4x−3 = 11 2) 2−5x = 4 3) 3 2
x−2 = 6 4) 6x−4 = 3x + 14
il faut resoudre ces equations

Bonjour,

4x - 3 = 11

4x = 11 + 3

4x = 14

x = 14/4 = 7/2

2 - 5x = 4

- 5x = 4 - 2

- 5x = 2

x = -2/5

32x - 2 = 6

32x = 6 + 2

32x = 8

x = 8/32 = (8 * 1)/(8 * 4) = 1/4

6x - 4 = 3x + 14

6x - 3x = 14 + 4

3x = 18

x = 18/3 = 6
