Using Solver to solve Equations !

Hello,

I am facing a problem writing some formula equations in Excel to solve them with Solver.

When I write the formulas of the equations:

lnx+x2-2x=0

lnx-ex-3x=0

It appears an error message: 

I tried to modify options in Excel as indicated in the guide, but still no positive result.

Can you help me.

Thanks,

Fatjoni
