Verified answer

3/4x = 5

donc x = 5 / 3/4 = 5*4/3 = 20/3

4x - 3 = 11

4x = 11 + 3

x = 14/4 = 7/2

7 - 8x = 56

-8x = 56 - 7

x = -49/8

6x - 4 = 3x + 14

6x - 3x = 14 + 4

3x = 18

x = 6

allez je te laisse le e pour la forme

C’est vrai ce qu’il a dit mais:

e) 9-2x=11+4x

9-11=6x

6x=-2

x=-1/3
