This word problem can be represented by this equation\r
\n" ); document.write( "\n" ); document.write( "4n + 9 = 1/3n + 31\r
\n" ); document.write( "\n" ); document.write( "we subtract 9 from both sides of the equation\r
\n" ); document.write( "\n" ); document.write( "4n = 1/3n + 22\r
\n" ); document.write( "\n" ); document.write( "we then multiply both sids of the equation by 3\r
\n" ); document.write( "\n" ); document.write( "12n = n + 66\r
\n" ); document.write( "\n" ); document.write( "subtact n from both sides\r
\n" ); document.write( "\n" ); document.write( "11n = 66\r
\n" ); document.write( "\n" ); document.write( "and dividing both sides by 11 we get n = 6
\n" ); document.write( "
\n" );
