In 4 years, Nan will be 3 times as old as Dan will be then. The sum of their ages now is 56\r
\n" ); document.write( "\n" ); document.write( "hi,\r
\n" ); document.write( "\n" ); document.write( "Let x = age of Nan today\r
\n" ); document.write( "\n" ); document.write( "y = age of dan today\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x+4 = 3(y+4)
\n" ); document.write( "x+y = 56\r
\n" ); document.write( "\n" ); document.write( "Then\r
\n" ); document.write( "\n" ); document.write( "x = 3y+12-4 = 3y+8\r
\n" ); document.write( "\n" ); document.write( "3y+8+y = 56\r
\n" ); document.write( "\n" ); document.write( "4y = 48\r
\n" ); document.write( "\n" ); document.write( "y = 12
\n" ); document.write( "x = 44\r
