Bonsoir je suis en 6° qui pourrait m'aider a mon devoirs de maths il y a deux questions c la 9 et 10 c comme un Sudoku sauf que la c des carrés magique un peux

Bonsoir,

a | 6 | b | 4
c | d | e. | 5
2 | 3 | 8 | f
7 | g | 1 | h

Somme : 34

• 2 + 3 + 8 + f = 34
• f = 34 - 13 = 21

• 4 + 5 + f + h = 34
• h = 34 - 9 - 21 = 4

• 7 + g + 1 + h = 34
• g = 34 - 8 - 4 = 22

• 6 + d + 3 + g = 34
• d = 34 - 9 - 22 = 3

• a + d + 8 + h = 34
• a = 34 - 8 - 3 - 4 = 19

• a + 6 + b + 4 = 34
• b = 34 - 10 - 19 = 5

• a + c + 2 + 7 = 34
• c = 34 - 9 - 19 = 6

• b + e + 8 + 1 = 34
• e = 34 - 9 - 5 = 20

19 | 6 | 5 | 4
6 | 3 | 20 | 5
2 | 3 | 8 | 21
7 | 22 | 1 | 4

Deuxième carré magique :

15 | a | b | 12
c | d | 10 | 7
8 | e | f | g
3 | h | 13 | 0

Somme : 30

• 15 + c + 8 + 3 = 30
• c = 30 - 26 = 4

• c + d + 10 + 7 = 30
• d = 30 - 17 - 4 = 9

• 12 + 7 + g + 0 = 30
• g = 30 - 19 = 11

• 15 + d + f + 0 = 30
• f = 30 - 15 - 9 = 6

• 3 + h + 13 + 0 = 30
• h = 30 - 16 = 14

• 3 + e + 10 + 12 = 30
• e = 30 - 25 = 5

• 8 + e + f + g = 30
• f = 30 - 8 - 5 - 11 = 6

• b + 10 + f + 13 = 30
• b = 30 - 23 - 6 = 1

• 15 + a + b + 12 = 30
• a = 30 - 27 - 1 = 2

15 | 2 | 1 | 12
4 | 9 | 10 | 7
8 | 5 | 6 | 11
3 | 14 | 13 | 0

Remplis la grille :

- - A | B | C | D | E
1 | 7 | a | b | • | 7
2 | • | c | 7 | d | e
3 | f | 7 | • | 7 | g
4 | h | • | 7 | i | 7
5 | 7 | j | k | • | l

f + 7 = 9 => f = 2
7 + g = 11 => g = 11 - 7 = 4
b + 7 = 13 => b = 6
7 + k = 7 => k = 0
7 + i + 7 = 22 => i = 8
f + h + 7 = 18 => h = 18 - 9 = 9
7 + j + k = 15 => j = 15 - 7 = 8
7 + a + b = 16 => a = 16 - 13 = 3
a + c + 7 = 15 => c = 15 - 10 = 5
d + 7 + i = 24 => d = 24 - 15 = 9
c + 7 + d + e = 25 => e = 25 - 21 = 4
7 + e + g + 7 + l = 30 => l = 30 - 22 = 8

...|A | B | C | D | E
1 | 7 | 3 | 6 | • | 7
2 | • | 5 | 7 | 9 | 4
3 | 2 | 7 | • | 7 | 4
4 | 9 | • | 7 | 8 | 7
5 | 7 | 8 | 0 | • | 8
