e^2.5x / (e^(0.1x) + 3) = 10

e^(2.5x - 0.1x) + 1/3 = 10

e^2.4x = 29/3

ln^(e^(2.4x)) = ln(29/3)

2.4x = ln(29/3)

x = 0.945

Is that correct?

**Damon**, Saturday, January 24, 2009 at 6:35pmLet e^.1 x = y

25 y /(y+3) = 10

25 y = 10 y + 30

15 y = 30

y = 2

so

e^.1 x = 2

ln e^.1x = ln 2

.1 x = ln 2

x = 10 ln 2

= 6.931
