bonjour, pouvez vous m'aider a résoudre ces équations 5x+4=6 4x-5=7 6x+1=-5 2x=4= 5x-3=2 3x-5=-2 2x+6=-3

a=5x+4=6
a=5x=6-4
a=5x=2
b=4x-5=7
b=4x=7+5
b=4x=12
c=6x+1=-5
c=6x=-5-1
c=6x=-6
d=2x=4
e=5x-3=2
e=5x=2+3
e=5x=5

bonjour

5 x = 6 - 4 = 2
x = 2/5

4 x - 5 = 7
4 x = 7 + 5 = 12
4 x = 12/4 = 3

6 x  + 1 = - 5
6 x = - 5 - 1
6 x = - 6
x = 0

2 x = 4
x = 4/2 = 2

5 x - 3 = 2
5 x = 2 + 3 = 5
x = 1

3 x - 5 = - 2
3 x = - 2 + 5
3 x = 3
x = 1

2 x +6 = - 3
2 x = - 3 - 6
2 x = - 9
x = - 9/2
