I am trying to solve

*Use common or natural logarithms to solve symbolically.*

2e^2x+2= 6

first I divide both sides by 2

e^2x+2= 6 Mr F says: This line is wrong. You have to divide all terms by 2, not just the first ....... e^2x + 1 = 3. Personally, my first step would be to subtract 2 from both sides: 2 e^2x = 4 .......

use natural logarithms

ln e^2x+2 = ln 6

Simplify

2x+2 = ln 6

subtract 2 from both sides

2x = ln 6-4

Divide by 2

x = ln 6-4/2

I enter this into my Ti-83plus

ln (6-4)/2

my answer is .34657 It is wrong I figure it is the way I have entered it into the calc. Anybody have any thoughts of what is wrong?
