The sum of the ages of a father and a son is 52 years.
\n" ); document.write( "x + y = 52
\n" ); document.write( ":
\n" ); document.write( "Eight years ago, the father was eight times as old as his son.
\n" ); document.write( "x - 8 = 8(y - 8)
\n" ); document.write( "x - 8 = 8y - 64
\n" ); document.write( "x = 8y - 64 + 8
\n" ); document.write( "x = 8y - 56
\n" ); document.write( ":
\n" ); document.write( "Back to the 1st equation: replace x with (8y-56)
\n" ); document.write( "(8y-56) + y = 52
\n" ); document.write( "8y + y = 52 + 56
\n" ); document.write( "9y = 108
\n" ); document.write( "y = \"108%2F9\"
\n" ); document.write( "y = 12 yrs is the son's age
\n" ); document.write( ":
\n" ); document.write( "I'll let you find x, the father's age
\n" ); document.write( ":
