document.write( "Let x be \"how many years ago . . . \"\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then you have this equation\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    20-x = 3*(14-x).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Simplify and solve\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    20 - x = 42 - 3x\r\n" );
document.write( "\r\n" );
document.write( "    3x - x = 42 - 20\r\n" );
document.write( "\r\n" );
document.write( "      2x   = 22\r\n" );
document.write( "\r\n" );
document.write( "       x   = 22/2 = 11.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  11 years ago.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.  11 years ago they were  20-11 = 9 years old (Cesar) and 14-11 = 3 years old (Marissa).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "               9/3 = 3.   ! Correct !\r\n" );
