Exercice 1

Si a = 9 alors 20 – a = 11

Si n = 13 alors n – 7 = 6

Si y = 4 alors 2 + y = 6

Si x = 6 alors 8x = 48

Si n = 7 alors 6 + n = 13

Si y = 1 alors y + 6 = 7

Si z = 4 alors z² = 16

Si x = 7 alors x² = 49

Si n = 10 alors n² = 100

Si a = 3 alors 21 – a = 18

Si n = 1 alors 4 – n = 3

Si x = 7 alors x + 8 = 15

Si x = 19 alors x – 5 = 14

Si y = 8 alors y² = 64

Exercice 2

29 + 29 = 58

21 + 29 = 50

49 – 19 = 30

62 – 39 = 23

19 + 46 = 65

12 + 39 = 51

14 + 9 = 23

26 + 19 = 45

40 + 49 = 89

85 – 49 = 36

70 – 39 = 31

26 + 29 = 55

53 – 19 = 34

30 + 9 = 39

74 – 49 = 25

63 – 19 = 44

19 + 45 = 64

31 + 49 = 80

19 + 19 = 38

20 + 29 = 49
