Let x = the second number
\n" ); document.write( " x-6 = the first number
\n" ); document.write( "3(x-6)= the third number\r
\n" ); document.write( "\n" ); document.write( "The sum of three numbers is 111.
\n" ); document.write( "x-6+x+3(x-6)=111
\n" ); document.write( " x-6+x+3x-18=111
\n" ); document.write( " 5x-24=111
\n" ); document.write( " 5x=135
\n" ); document.write( " x=27\r
\n" ); document.write( "\n" ); document.write( "Substitute x for 27
\n" ); document.write( "27-6=21
\n" ); document.write( "3(27-6)=63\r
\n" ); document.write( "\n" ); document.write( "The numbers are 21,27 and 63.
\n" ); document.write( "
