bonjour

[tex]5 x + 7 = 3 x + 1 \\5 x - 3 x = 1 - 7 \\2 x = - 6 \\x = - 3 \\\\- 2 x - 3 = 4 x - 6 \\- 2 x - 4 x = - 6 + 3 \\- 6 x = - 3 \\x = 3/6 = 1 /2 \\\\10 x - 2 = 7 x - 7 \\10 x - 7 x = - 7 + 2 \\3 x = - 5 \\x = - 5/3[/tex]

Bonjour;

5x+7=3x+1

5x-3x = 1-7

2x = -6

x = -6/2

x = -3

-2x-3=4x-6

-3+6 = 4x+2x

3= 6x

x =3/6

x = 0,5

10x-2=7x-7

10x-7x = -7 +2

3x = -5

x = -5/3
