Using Solver to solve Equations !

Copper Contributor

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: 

#NUM!

 

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

 

Can you help me.

 

Thanks,

Fatjoni
