This is a far as I got, it is actually a small part in a huge calculus problem.

These equations can't be solved by algebra. You have to use numerical methods to get the answer to any desired degree of accuracy. Basically it's guess and improve or possibly use series.
You will often find that mixtures of different types of functions, trig, polynomial, ln, exp., can't be solved.
Do you need a quick idea of numerical methods?

first one doesnt have an analytic solution, you have to solve numerical / graphical
graphical :
ln(x) - x +2 = 0 =>ln(x) = x -2
draw the graph of ln(x) and of the line x-2,
where they cross is the x you are looking for.
second one..
well i guess its not solvable analytical either
