Pour B : B = (A + 26)/2 B = (A/2) + (26/2) B = (A/2) + 13 Donc : B = (((5 + B)/2)/2) + 13 B = ((5 + B) / 4) + 13 B = ((5 + B) + (13 x 4))/4 4B = 5 + B + 52 4B - B = 5 + 52 3B = 57 B = 57/3 B = 19
D'où : A = (5 + B)/2 A = (5 + 19)/2 A = 24/2 A = 12
Pour C : 26 = (B + C)/2 C = (26 x 2) - B C = 52 - B C = 52 - 19 C = 33
Conclusion :
A = 12 - B = 19 - C = 33 Donc : 5 - 12 - 19 - 26 - 33

Verified answer
Pour A :
A = (5 + B)/2
Pour B :
B = (A + 26)/2
B = (A/2) + (26/2)
B = (A/2) + 13
Donc :
B = (((5 + B)/2)/2) + 13
B = ((5 + B) / 4) + 13
B = ((5 + B) + (13 x 4))/4
4B = 5 + B + 52
4B - B = 5 + 52
3B = 57
B = 57/3
B = 19
D'où :
A = (5 + B)/2
A = (5 + 19)/2
A = 24/2
A = 12
Pour C :
26 = (B + C)/2
C = (26 x 2) - B
C = 52 - B
C = 52 - 19
C = 33
Conclusion :
A = 12 - B = 19 - C = 33
Donc :
5 - 12 - 19 - 26 - 33
