Three possible values:
\n" ); document.write( " $\"x%2B5=4\"$
\n" ); document.write( " $\"x=-1\"$
\n" ); document.write( "Not allowed since one side would be $\"2%28-1%29-1=-3\"$
\n" ); document.write( " $\"2x-1=4\"$
\n" ); document.write( " $\"2x=5\"$
\n" ); document.write( " $\"highlight%28x=5%2F2%29\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( " $\"x%2B5=2x-1\"$
\n" ); document.write( " $\"highlight%28x=6%29\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "In fact, only two value of x make the triangle isoceles.
