\n" ); document.write( "A father is 43 and he has two kids who are 9 and 11. How many years have to go by so that the ages of the two kids equal the age of the father?\r

\n" ); document.write( "9 + x + 11 + x = 43
\n" ); document.write( "20 + 2x = 43
\n" ); document.write( "2x = 43\r
\n" ); document.write( "\n" ); document.write( "But it doesn't seem to make sense to have a decimal age for x.
\n" ); document.write( "

(9+x) + (11+x) = (43+x)
\n" ); document.write( ":
\n" ); document.write( "2x +20 = 43 +x
\n" ); document.write( ":
\n" ); document.write( "x = 23
