Bonjour, besoin d'aide merci resoudre les inequations [tex]2x-3 (x+1) \leq 5+x[/tex] [tex]2(x+1)-3 (2-x) \leq 4(1-x)[/tex] [tex]X-1/2 \leq 2x+1/3[/tex]

bonjour
2x-3(x+1) ≤5+x
2x - 3x - 1 ≤ 5 +x
2x -3x -x ≤ 5 +1
-2x ≤ 6
x ≥ 6/2
x≥ 3

2(x+1) -3(2-x)≤ 4(1-x)
2x +2 - 6 +3x ≤ 4 - 4x
2x +3x +4x ≤ 4 -2 +6
9x ≤ 8
x≤ 8/9

x-1/2≤ 2x +1/3
6x - 3 ≤ 12x + 2
6x -12x ≤ 2 +3
-6x ≤ 5
x ≥ -  5/6
