When u reverse the digits of age of father u will get the age of son.
\n" ); document.write( "10x + y = father's age
\n" ); document.write( "10y + x = son's age
\n" ); document.write( ":
\n" ); document.write( "one year ago the age of father was twice that of son's age.
\n" ); document.write( "10x + y - 1 = 2(10y + x - 1)
\n" ); document.write( "10x + y - 1 = 20y + 2x - 2
\n" ); document.write( "10x - 2x = 20y - y - 2 + 1
\n" ); document.write( "8x = 19y - 1
\n" ); document.write( "x = $\"19%2F8\"$ y - $\"1%2F8\"$
\n" ); document.write( "Only one set of single digit integers will satisfy this equation
\n" ); document.write( "y = 3; x = 7
\n" ); document.write( ":
\n" ); document.write( " what are the current ages of father and son?
\n" ); document.write( "Dad is 73, son is 37
\n" ); document.write( ":
\n" ); document.write( "Check one year ago
\n" ); document.write( "Dad is 72, son is 36, half Dad's age \n" ); document.write( "

\n" );
