\r\n" );
document.write( "Let S be the son's present age.\r\n" );
document.write( "Then the daughter's age is S-3 years now and the father's age is 3S years now.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "3 years ago the son age was (S-3), the daughter's age was (S-6) and the father's age was 3S - 3.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, your equation is \r\n" );
document.write( "\r\n" );
document.write( "(S-3) + (S-6) + (3S-3) = 63 .\r\n" );
document.write( "\r\n" );
document.write( "Simplify and solve for S:\r\n" );
document.write( "\r\n" );
document.write( "5S - 12 = 63  --->  5S = 75  ---->  S = \"75%2F5\" = 15.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, the son is 15 years old now.\r\n" );
document.write( "\r\n" );
