Bonjour,
1. 5 x 3 = =15
2-6 + 4 + 2 + 7 = 9
3.3 +2=5
4. (-2)(-) = ? ( incomplet)
5. 3x - 2 - 3 - 9 = 3x-14
6.2 X 6 = =12
7.3 - 5 = = -2
8. XXI =?
9. 2x x 4 = 8x
10. = 7* -r-72) = 7r-72
11. 2x x 2x + 2x) =4x² +2x
12. 5x – 2x + 5 =3x+5
13. -5 + 7 + 7 + 6 = 15
14. 2x - x = x
15. -4 + 6 + 6 2x=??
16.5 x 3r = 15r
17. -5 - 3r = -5-3r
18.5(-32) = -160
19.2 + 6 - 2x = -2x +8
20.-7x - x = -8x
21.(-3x)(-5x) = 15x²
