where is the mistake?
everything follows up well, but when I compare the result (eq. 5) with the numerical solution of eq. 1, then are different. Where is the mistake? eq. 3?

The mistake is in the integration of eq. because
exp(kt)dx isn't equal to d(x exp(kt) )
So, Eq. is false.
Do not forget that t is function of x.
t(x) is the reciprocal function of x(t)
So you would have to integrate exp(kt(x))dx, not simply exp(kt)dx with t constant.
