Hello,
I am in differential equations, but it always seems that its my algebra that trips me up. Can anybody tell me how to solve for t in the following expression?:
-8.9 = t - ln(21.34t)
thanks!!

This equation doesn't have a real solution:
1. Consider the RHS of the equation as a function in t.
2. This function $\displaystyle f(t)=t-\ln(21.34 \cdot t)$ has an absolute minimum at $\displaystyle M(1, -2.0606)$
3. The graph of f never intersects the graph of y = -8.9
