allez termine les dernières, c'est pareil

Bonjour,

4a+3 = a-8

4a- a = -8 -3

3a = -11

a = -11/3

-5c -3 = 2c

-3 = 2c+5c

-3 = 7c

c= -3/7

7y = y+3

7y-y = 3

6y = 3

y = 3/6 = 1/3

x+1 = 5x+2

1-2 = 5x -x

-1 = 4x

x= -1/4

6x-4 = 3x+14

6x-3x= 14 -4

3x = 10

x= 10/3

9-2x  = 11+4x

9-11 = 4x +2x

-2 = 6x

x= -2/6 = -1/3
