Salut aidez moi svp AP2 - Equations du 1er degré : Résoudre les équations suivantes SANS calculatrice :

1°) 3 +4 -2x+9

2°) 2 x + 3 = 3 - 5

3°) 5x-1=2 x +4

4°) 3 x + 1 =7 x + 5

5°)5x+8=0

6) 5 - 4 x=0

7°) 5 x + 2 = 9 x + 7

8°) 5 - (x-3) = 4x -3x-8)

9) 2+x-(5+2x) - 7= 3 x + 7

10) 4x +3 - (x + 1) + 5 = 5 x +7

11°) 2 x + 1 - (2 + x) - 7 = 3 x 7

12) 5(x-1)+3(2-x) - 0

13) 7(x + 4) - 3 (x + 2) = x+7

14) 2 (x-1)-3 (x + 1) = 4(x-2)

15) 8 (4- 3 x) + 1 - 53 - 3(x - 5)

16°) 13 x + 2 (x-3) = x-5-3 (x + 12)

17º) 5 (3 x-1)-(1-2 x) = 3 (5.x-2)

18) (x + 2)(x+1)-(x+4) (x-5)

19°) 3 x +3=2-7

20) x +4=2x-5 +4 = 2
