Let n be the number, then from the problem description, you can write:
\n" ); document.write( "\"Two times the sum of the number and three is the same as (=) nine subtracted from three times the number.\"
\n" ); document.write( "2(n+3) = 3n-9 Simplify.
\n" ); document.write( "2n+6 = 3n-9 Subtract 2n from both sides.
\n" ); document.write( "6 = n-9 Add 9 to both sides.
\n" ); document.write( "15 = n
\n" ); document.write( "The number is 15.\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
