\r\n" );
document.write( "x = smallest odd integer of the three \r\n" );
document.write( "x+2 = middle odd integer of the three\r\n" );
document.write( "x+4 = largest odd integer of the three

the sum of the largest and twice the smallest is 12 more than the middle number

\r\n" );
document.write( "\r\n" );
document.write( " (x+4)  + 2*(x) = (x+2) + 12\r\n" );
document.write( "  x+4   + 2x    =  x+2  + 12\r\n" );
document.write( "        3x + 4  =  x + 14\r\n" );

document.write( "             x  =  5\r\n" );
document.write( "\r\n" );
document.write( " x = smallest odd integer of the three = 5 \r\n" );
document.write( "x+2 = middle odd integer of the three = 5+2 = 7\r\n" );
document.write( "x+4 = largest odd integer of the three = 5+4 = 9\r\n" );
document.write( "\r\n" );
document.write( "We check the numbers in the words:

3 consecutive odd integers

5, 7, and 9 are all odd and consecutive. That checks.

such that the sum of the largest and twice the smallest

The largest is 9.  Twice the smallest is two time 5, or 10. \r\n" );
document.write( "Their sum, when we add those, 9+10 is 19

is 12 more than the middle number.

Indeed! The middle number is 7, and 19 is 12 more than 7.\r\n" );
