document.write( "Let x be the present age of her student.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then Jessa's present age is (x+15) years.\r\n" );

document.write( "    2*((x+15) + 15) = 3*(x+15).\r\n" );

document.write( "\r\n" );
document.write( "    60 - 45 = 3x - 2x  ====>  x = 15.   <<<---=== the student's present age.    ANSWER\r\n" );

document.write( "\r\n" );
document.write( "CHECK.  Then Jessa's present age is 15 + 15 = 30 years.   (\"Jessa is 15 years older than her student.\")\r\n" );

document.write( "        2*45 = 90 = 3*30.     ! Precisely correct !\r\n" );
