Réponse:
N:
x/4 = 9
4 × 9 = 36
36/4 = 9 (x = 36)
E:
3x – 11 = 9x + 4
3x - 9x = 11 + 4
-6x = 15
x = 15/(-6) = -2,5
M:
5x + 5 = 4x – 7
5x – 4x = -5 – 7
1x = -12
x = -12/1 = -12
I:
5x – 15 = -2x – 13
5x + 2x = 15 – 13
7x = 2
x = 2/7
A:
x – 2 = -2x + 4
(1)x + 2x = 2 + 4
3x = 6
x = 6/3 = 2
D:
4x + 15 = -2x + 3
4x + 2x = -15 +3
6x = -12
x = -12/6 = - 2
