1. Réponse maudmarine
2 (x + 3) = 1
2x + 6 = 1
2x = 1 - 6
2x = - 5
x = - 5/2
x = - 2,5
2x - 3 = 1
2x = 1 + 3
2x = 4
x = 4/2
x = 2
2 (x + 3) = 3
2x + 6 = 3
2x = 3 - 6
2x = - 3
x = - 3/2
x = - 1,5
2x + 3 = 1
2x = 1 - 3
2x = - 2
x = -2/2
x = - 1
x + 3 = 2
x = 2 - 3
x = - 1
3x = 2
x = 2/3
x - 3 = 2x
x - 2x = 3
- x = 3
x = - 3
