\"Eight is my lucky number. Eight years ago I was eight times the
\n" ); document.write( "age of my son. Today the sum of our ages is 52 - you tell me how old I am.\"
\n" ); document.write( "

\n" ); document.write( "Let mine and my son's current ages be M, and S, respectively
\n" ); document.write( "Then we can say that: M - 8 = 8(S - 8)_____M - 8 = 8S - 64
\n" ); document.write( "M - 8S = - 64 + 8____M - 8S = - 56 ------ eq (i)
\n" ); document.write( "Also, M + S = 52_______S = 52 - M ------- eq (ii)\r
\n" ); document.write( "\n" ); document.write( "M - 8S = - 56 ------ eq (i)
\n" ); document.write( "M - 8(52 - M) = - 56 ------- Substituting 52 - M for S in eq (i)
\n" ); document.write( "M - 416 + 8M = - 56
\n" ); document.write( "9M = - 56 + 416
\n" ); document.write( "9M = 360
\n" ); document.write( "M, or my age = \"highlight_green%28highlight_green%2840%29%29\" \n" ); document.write( "
\n" );
