bonjour j'ai besoin d'aide pour mon DM de maths merci beaucoup​

Bonjour,

7(4x+1) = 28x+7

3(x-5) = 3x-15

8(3x-1) = 24x-8

7(2x-1) = 14x-7

4(3x+4) = 12x+16

2(x+1) = 2x+2

3(2-3x) = 6-9x

7(x-6) = 7x-42

2(4x+1) = 8x+2

8(x-3) = 8x-24

5(2x+6) = 10x+30

7(3x+1) = 21x+7

4(3x-2) = 12x-8

5(4-3x) = 20-15x

3(3x+9) = 9x+27

2(2x-1) = 4x-2

5(1-x) = 5-5x

3(2x+4) = 6x+12

5(2x+1) = 10x+5

et

4(3-2x) = 12-8x
