Pour résoudre l'équation e \cdot 2n + 7en - 8 = 0 , on commence par factoriser par regroupement :

e \cdot 2n + 7en - 8 = 0

2en + 8en - e - 8 = 0

2en(1+4) - 1(1+8) = 0

2en \cdot 5 - 1 \cdot 9 = 0

Ensuite, on factorise l'expression obtenue :

10en - 9 = 0

10en = 9

e = \frac{9}{10n}

Donc, la solution de l'équation est e = \frac{9}{10n} .

\boxed{e = \frac{9}{10n}}
