for some reason im stuck on this: 2=e^(x-1)-e^(1-x)
i changed the 2 into e^(Ln2) and then removed the e's
i got this:
Ln2 = x-1-1+x
and then finally
x= (2+Ln2)/2
its wrong, but im not sure why

ln(e^(x-1) - e^(1-x)) doesn't becomes (x-1) - (1-x) (you cant just remove the e's)

#

my solution for this involves making it into quadratic form and solving it that way
