1. ## solving logarithm/exponential equations

I've come across a couple log equations in which I'm having trouble solving for x. Any help will be appreciated

a: 3e^(-x+1) = 5 -x^2

b: ln(.5x)=.2 - e^x

2. ## Re: solving logarithm/exponential equations

Elementary algebraic methods will not yield exact, closed-form solution(s) for either of these equations ... you'll have to resort to numerical methods to approximate them.

$3e^{1-x} = 5-x^2$

$\ln(x/2) = 0.2-e^x$
