$\"+ln+%28+4x+-+8%29+%96+ln+%28+x-1+%29+=+ln+%28+5+%29+\"$
\n" ); document.write( " $\"+ln%284%29+%2B+ln%28+x-2+%29+-+ln%28+x-1+%29+=+ln%285%29+\"$
\n" ); document.write( " $\"++ln%28+x-2+%29+-+ln%28+x-1+%29+=+ln%285%29+-+ln%284%29+\"$
\n" ); document.write( " $\"+ln%28+%28+x-2+%29+%2F+%28+x-1+%29+%29+=+ln%28+5%2F4%29+\"$
\n" ); document.write( " $\"+%28+x-2+%29+%2F+%28+x-1+%29+=+5%2F4+\"$
\n" ); document.write( " $\"+4%2A%28+x-2%29+=+5%2A%28+x-1+%29+\"$
\n" ); document.write( " $\"+4x+-+8+=+5x+-+5+\"$
\n" ); document.write( " $\"+x+=+-3+\"$
\n" ); document.write( "This can't be right because it gives me
\n" ); document.write( " $\"+ln%28-20%29+\"$ and $\"+ln%28-4%29+\"$
\n" ); document.write( "It is impossible to have ln( a negative number )
\n" ); document.write( "-------
\n" ); document.write( "I'll try something different
\n" ); document.write( " $\"+%28+x-2+%29+%2F+%28+x-1+%29+=+1+-+%28+1%2F%28+x-1%29%29+\"$
\n" ); document.write( " $\"+1+-+%28+1%2F%28+x-1%29%29++=+5%2F4+\"$
\n" ); document.write( " $\"+1%2F%28+x-1+%29+=+4%2F4+-+5%2F4+\"$
\n" ); document.write( " $\"+1%2F+%28+x-1+%29+=+-+%281%2F4%29+\"$
\n" ); document.write( " $\"+x+=+-3+\"$
\n" ); document.write( "Still impossible. I think either the problem can't be solved
\n" ); document.write( "or it was copied wrong. \n" ); document.write( "
