http://ask.sagemath.org/question/32563/solve-exponential/

var('t','k1','k2','y1','y2')
assume(k1>0,k2>0,y1>0,y2>0)
assume(k1,'real')
assume(k2,'real')
assume(y1,'real')
assume(y2,'real')
assume(t,'real')
solve(y1*exp(-t/k1)/k1 - y2*exp(-t/k2)/k2==0,t)

Apparently sympy behaves more as expected.

Component: calculus
