n
- 3 n
- 3 n + 5
2 ( - 3 n + 5 )
2 ( - 3 n + 5) + 6 n
- 6 n + 10 + 6 n
= 10
on trouvera toujours 10
- 7
- 7 *- 3 = 21
21 + 5 = 26
26 * 2 = 52
52 - 42 = 10
2/7
2/7 * - 3 = - 6/7
- 6/7 + 5 = - 6/7 + 35/7 = 29/7
29/7 * 2 = 58/ 7
58/7 + 12/7 = 70/7 = 10
6 + 5 = 11
ont donné un RDV : 55 x 6 /11 = 30
30 ont dit oui
