Tim is three years older than his younger sister Kayla.
T = K+3
The sum of the two ages is 9.
T+K = 9\r\n" );
document.write( "\r\n" );
document.write( "Substitute K+3 for T\r\n" );
document.write( "\r\n" );
document.write( "K+3+K = 9\r\n" );
document.write( " 2K+3 = 9\r\n" );
document.write( "   2K = 6\r\n" );
document.write( "    K = 3\r\n" );
document.write( "\r\n" );
document.write( "Kayla is K, and K = 3, so Kayla is 3.\r\n" );
document.write( "\r\n" );
document.write( "Tim is T, or T = K+3 = 3+3 = 6, So Tim is 6.\r\n" );
document.write( "\r\n" );
