No, you can`t do that
ln(y)= X+ 2
y = e^(x+2)

You must learn how to change a log equation to an exponential equation:

By the definition of a logarithm:

logB(A) = C can be written as A = BC 

And we know that "ln" is an appreviation for loge


ln(y) = x+2

is the same as  

loge(y) = x+2

which can be changed to the exponential equation:

y = ex+2
