John is currently 4 times as old as his daughter, Linda.

\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "J = 4•L\r\n" );
document.write( "

\n" ); document.write( "Six years from now, John will be 3 times as old as Linda.
\n" ); document.write( "

\r\n" );
document.write( "(John + 6 = 3×(Linda + 6)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "  J + 6 = 3•(L + 6)\r\n" );
document.write( "\r\n" );
document.write( "So you have these two equations:\r\n" );
document.write( "\r\n" );
document.write( "      J = 4•L\r\n" );
document.write( "  J + 6 = 3•(L + 6)\r\n" );
document.write( "\r\n" );
document.write( "Substitute 4•L from the first equation \r\n" );
document.write( "in place of J in the second equation:\r\n" );
document.write( "\r\n" );
document.write( "4•L + 6 = 3•(L + 6)\r\n" );
document.write( "\r\n" );
document.write( "You finish.\r\n" );
