Bonsoir

a) 4 x + 2 + 3 x = 5 + 2 x + 12
a) 7 x - 2 x = 5 + 12 - 2
5 x = 15
x = 3

b) 5 + x + 2 = 4 x + 1 + 2
x - 4 x = 1 + 2 - 5 - 2
- 3 x = - 4
x = 4/3

c) 3 x + 6 = 4 x + 12
3 x - 4 x = 12 - 6
- x = 6
x = - 6

d) 3 x + 4 + x + 1 = 2 x + 4
4 x - 2 x = 4 - 4 - 1
2 x = - 1
x = - 1/2

Exercice 38 :

a) 4x + 2 + 3x = 5 + 2x + 12
7x + 2 = 17 + 2x
7x - 2x = 17 - 2
5x = 15
x = 15/5
x = 3

b) 5 + (x + 2) = (4x + 1) + 2
5 + x + 2 = 4x + 1 + 2
7 + x = 4x + 3
x - 4x = 3 - 7
- 3x = - 4
x = - 4 / (- 3)
x = 4/3

c) 3 (x + 2) = 4 (x + 3)
3 * x + 3 * 2 = 4 * x + 4 * 3
3x + 6 = 4x + 12
3x - 4x = 12 - 6
- x = 6
x = - 6

d) (3x + 4) + (x + 1) = 2 (x + 2)
3x + 4 + x + 1 = 2 * x + 2 * 2
4x + 5 = 2x + 4
4x - 2x = 4 - 5
2x = - 1
x = - 1/2
x = - 0,5
