Si la réponse est bonne, le quiz passedirectement à la question suivante !
Répondre au hasard neprésente aucun intérêt...
2x + 4 = 6
x = 2
x = 1
a pour solution...
2x + 4 = 6
x = 1
a pour solution...
2x + 4 = 62x = 6 - 42x = 2x = 2 : 2x = 1
Solution
-2x + 5 = 7
x = -1
x = 2
a pour solution...
-2x + 5 = 7
x = -1
a pour solution...
-2x + 5 = 7-2x = 7 - 5-2x = 2x = 2 : (-2)x = -1
Solution
4x + 2 = -6
x = 3
x = -2
a pour solution...
4x + 2 = -6
x = -2
a pour solution...
4x + 2 = -64x = -6 - 24x = -8x = -8 : 4x = -2
Solution
-2x - 6 = -16
x = 4
x = 5
a pour solution...
-2x - 6 = -16
x = 5
a pour solution...
-2x - 6 = -16-2x = -16 + 6-2x = -10x = -10 : (-2)x = 5
Solution
12 = 2x + 4
x = 2
x = 4
a pour solution...
12 = 2x + 4
x = 4
a pour solution...
12 = 2x + 4ou2x + 4 = 122x = 12 - 42x = 8x = 8/2x = 4
Solution
20 = -5x + 5
x = -3
x = 5
a pour solution...
20 = -5x + 5
x = -3
a pour solution...
20 = -5x + 5ou-5x + 5 = 20-5x = 20 - 5-5x = 15x = 15 : (-5)x = -3
Solution
-8 = -5x + 2
x = 2
x = 4
a pour solution...
-8 = -5x + 2
x = 2
a pour solution...
-8 = -5x + 2ou-5x + 2 = -8-5x = -8 - 2-5x = -10x = -10 : (-5)x = 2
Solution
-25 = 5x - 5
x = 6
x = -4
a pour solution...
-25 = 5x - 5
x = -4
a pour solution...
-25 = 5x - 5ou5x - 5 = -255x = -25 + 55x = -20x = -20 : 5x = -4
Solution
10x + 2 = 2
x = 0
x = 1
a pour solution...
10x + 2 = 2
x = 0
a pour solution...
10x + 2 = 210x = 2 - 210x = 0x = 0
Solution
4x - 2 = -4
x = -0,5
x = -2
a pour solution...
4x - 2 = -4
x = -0,5
a pour solution...
4x - 2 = -44x = -4 + 24x = -2x = -2 : 4x = -0,5
