si la ecuacion es:
%ea = 100k (21/(21- %oxigeno) -1)
entonces %oxigeno es igual a:
%ea/100k = 21/(21-%oxigeno) -1
%ea/100k + 1 = 21/(21-%oxigeno)
(%ea/100k + 1) * (21-%oxigeno)= 21
(21-%oxigeno)= 21 /(%ea/100k + 1)
-%oxigeno= 21 /(%ea/100k + 1) -21
%oxigeno= -1 * ( 21 /(%ea/100k + 1) -21)

%ea/(k*100)=21/(21-%O)-1
(%ea/(k*100))+1=21/(21-%O)
(%ea/(k*100))+1)/21=1/(21-/%O)
Invierto ambas fracciones (elevo a la -1 en ambos miembros)
21/(%ea/(k*100)+1)=21-%O
21- 21/(%ea/(k*100)+1)= %O

Y = K(21/(21-X)-1)
Y(21-X)=K(21-(21-X))
Y(21-X)=K(21-21+X)
Y(21-X)=KX
21Y-XY=KX
21Y=KX+XY
21Y=X(K+Y)
X=21Y/(K+Y)
X=21(EA/100)/(K+(EA/100))
ENTOCES
%O = 21%EA/(100K+%EA)

Llamaré x al % oxígeno.
%ea = k * 21 / ( (21 -x) -1) *100
%ea = k * 21 / (21- x -1) *100
%ea * 100 / k * 21 = 1 / 20 -x
%ea * 100 (20 - x) = k * 21
20 - x = k *21 / %ea *100
-x = k *21 / %ea *100 -20
Siempre y cuando el 100 esté en el denominador. Si está multiplicando a K es distinta.
X = 20 - k*21 / %ea * 100
