Homework Statement



Do anyone know how to solve:
y=LN x
y=e+1-x


Homework Equations




y=LN x
y=e+1-x



The Attempt at a Solution



LN x=e+1-x
x=e^e * e^1 / e^x
x*e^x=e^(e+1)

then I don't know how to solve, must I solve it graphically?

Actually, the original question is :
Double integration
InIn x dxdy for the area bounded by y=e+1-x and y=LNx and x-axis

Trial and error shows [itex]x = e[/itex] is a solution to [itex]\ln{x} = e + 1 - x[/itex]. Closer inspection reveals the solution is unique because [itex]\ln{x}[/itex] is strictly increasing while [itex]e + 1 - x[/itex] is strictly decreasing.

I know not of an elementary technique for solving such an equation.
