warning :unable to find explicit solution

Hello,

If anybody can help me with this equation:

my variables

Trough : c

Dose : d

Vd : v

e : exponent 2.718

k : x

T infusion: f

t : t

here is my code:

syms c d v x f t
eqn = c==(((d/v)*exp(-x*f)+(c))*exp(-x*t))
solx = solve (eqn,x,"IgnoreAnalyticConstraints",1)

and this is the result:

I need to have an explicit eqaution to solve for K which is x in the equation.

I am using Matlab online

Thank you so much guys.

There is no explicit solution for k! However, Matlab would have no difficulty in finding numerical values given values for the other parameters.
