\n" ); document.write( "its pretty simple i think, this is what i've figured out.
\n" ); document.write( "
\n" ); document.write( "ln(e^(2x+5))=ln(40)
\n" ); document.write( "2x+5=ln(40)
\n" ); document.write( "2x+5 = 3.688

\n" ); document.write( "x = -1.344\r
\n" ); document.write( "\n" ); document.write( "im not sure if thats right, i didnt really pay attention in logs,and e's.

You can put this solution on YOUR website!
Quickest way to check is to plug your solution into the equation and make sure it solves it.

\n" ); document.write( "\"10.094\"
\n" ); document.write( "Oops, there's a problem.
\n" ); document.write( "You paid attention for logarithms but not during subtraction.
\n" ); document.write( "Your thinking and approach to the problem are clear.
