\r\n" );
document.write( "Five years ago, Sandra was 63 years older than her grandson  , at the same time, \r\n" );
document.write( "she was 4 times as old as the grandson.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Let x be the grandson age five years ago. Then Sandra's age five years ago is 4x,\r\n" );
document.write( "according to the problem's description.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So we can write an equation\r\n" );
document.write( "\r\n" );
document.write( "    4x - x = 63,  or  3x = 63,  which implies  x = 63/3 = 21.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Thus, five years ago the grandson was 21 years old;\r\n" );
document.write( "hence, Sandra was 4*21 = 84 years old five years ago.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, now Sandra is 84 + 5 = 89 years old.    ANSWER\r\n" );
