let f = father's present age
\n" ); document.write( "let s = son's age
\n" ); document.write( "let x = their age difference (f-s)
\n" ); document.write( ":
\n" ); document.write( "His father say \"when i was your age, you were 2 years old.
\n" ); document.write( "s = x + 2
\n" ); document.write( "His son replies\" when I reach your age, you will be 68?
\n" ); document.write( "s + x = 68 - x
\n" ); document.write( "s = 68 - x - x
\n" ); document.write( "s = 68 - 2x
\n" ); document.write( "s-s therefore
\n" ); document.write( "x + 2 = 68 - 2x
\n" ); document.write( "x + 2x = 68 - 2
\n" ); document.write( "3x = 66
\n" ); document.write( "x = 66/3
\n" ); document.write( "x = 22 yrs is the difference in their ages
\n" ); document.write( ":
\n" ); document.write( "Find s
\n" ); document.write( "s + 22 + 2
\n" ); document.write( "s = 24
\n" ); document.write( ":
\n" ); document.write( "\"What is his father present age ?
\n" ); document.write( "f = 24 + 22
\n" ); document.write( "f = 46 yrs is the father's age\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
