Équations Régionales

Un petit effort de compréhension est exigé !

Contexte 01

* A + B + C = T
100 + 100 + C = 200 => C = 0

* A + B + C = T
100 + 100 + C = 100 => C = – 100

Donc C = -100 = 0 ???

Contexte 02

* A + B + C = T
40 + 40 + C = 100 => C= 1/2 A = 1/2 B => C = 20

* A/10 + B/10 + C/10 = 10 => 5 + 5 + C/10 = 10 => C/10 = 0 => C = 0

Donc C = 20 = 0 ???

Contexte 03

A + B + C = T
Aa + Athr + C = 2 Ar =>  si  Aa = Athr = Ar  C = 0
Mais Aa > Athr => C > 0

Donc C > 0 = 0 ???
