Here's what we know:
\n" ); document.write( " $\"2%2F3\"$ x - $\"3%2F5\"$ x = 3
\n" ); document.write( "Let's use the common denominator 15
\n" ); document.write( " $\"10%2F15\"$ x - $\"9%2F15\"$ x = 3
\n" ); document.write( "Subtract
\n" ); document.write( " $\"1%2F15\"$ x = 3
\n" ); document.write( "Multiply each side by 15
\n" ); document.write( "1x = 45
\n" ); document.write( ".
\n" ); document.write( "Plug it in to prove.
\n" ); document.write( "( $\"2%2F3\"$ *45)-( $\"3%2F5\"$ *45)=3
\n" ); document.write( " $\"90%2F3\"$ - $\"135%2F5\"$ =3
\n" ); document.write( "30 = 27 = 3
\n" ); document.write( "Success! \n" ); document.write( "

\n" );
