pre-calc homework help plx

[wafflehammer]

uhmmmz k. Suppose to have a test on this last friday but i kinda got suspended. That means no test...and no help from teacher :\

Doing logarithmic equations and this one has got me confused.

Directions are "Solve the logarithmic equation for x"

I can do the ones like :

ln(2+x)=1

but then the ones like :

2-ln(3-x)=0 sneak up and slap me on the face. I have no clue what to do with the "2-" before the natural log....

any tips would be helpful.

ln(3-x)=2

thanks for making me feel dumb :]

uhm yea that worked

ln(3-x)=2
e^2=3-x
7.3891=3-x
7.3891-3=-x
4.3891=-x divide both by -1
-4.3891=x <----answer that was in the book...just didn't know how to get there lol

thanks hef :]
