- 18 Oct '10 20:32Does anyone see a clear cut solution analytic solution to the following equation?

I came across it in a homework problem, and couldn't seem to see the path to take. Its too late for the grade, and the course isn't in solving equations, but its troubling me that the writers would leave its solution to approximation methods.

-10^5*e^(-1/20*t) -10^4*t + 2*10^5 = 0
