#x=e^3#

Explanation:

First of all, let us start by doing simple changes:
#19+2lnx=25#
#2 lnx= 25-19#
#2lnx=6#
----------------------->>>>> we applied simple side by side manipulations, now we will do the division by 2 in both the sides, it will end up this:
#lnx=3#
--------------->>>>>> now we will use the inverse of ln, which is #e#
#e^(lnx)=e^3#
#x=e^3# ----->>> now you should use a calculator or the problem may have this as solution depending on the assignment guidelines.
