let the number be $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( "one-quarter of a number,: $\"x%2F4\"$ \r
\n" ); document.write( "\n" ); document.write( " one-half of the same number: $\"x%2F2\"$ \r
\n" ); document.write( "\n" ); document.write( "if $\"x%2F4\"$ increased by $\"x%2F2\"$ is twelve, we have\r
\n" ); document.write( "\n" ); document.write( " $\"x%2F4%2Bx%2F2=12\"$ .....both sides multiply by $\"4\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"4x%2F4%2B4x%2F2=4%2A12\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x%2B2x=48\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"3x=48\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=48%2F3\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=16\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the number is $\"16\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
