A differential equation on Kahn academy

I began to study Differential equations lately. It has been relentless days.

Tools I use:

Paper and digital text books

Pencil and printing papers

Scientific calculator

CAS (Computer Algebra System) – Sympy and ipython notebook

Knowing Kahn academy site was a bit surprise. I had spent few hours to see video lectures, and to pass exam of which are composed series of problems. The exam setup is intriguing. The student needs to give correct answers of the questions five in a row. One wrong answer after four right answers triggers another five questions to be solved.

My calculation of below question was x = e^-2.7011.
