six years ago, Teddy was 5 times as old as his daughter dianne.
\n" ); document.write( "t - 6 = 5(d - 6)
\n" ); document.write( "t - 6 = 5d - 30
\n" ); document.write( "t = 5d - 30 + 6
\n" ); document.write( "t = 5d - 24
\n" ); document.write( ":
\n" ); document.write( "How old is dianne if her age is half of her fathers age?
\n" ); document.write( "t = 2d
\n" ); document.write( ":
\n" ); document.write( "Replace t with 2d in the 1st equation
\n" ); document.write( "2d = 5d - 24
\n" ); document.write( "24 = 5d - 2d
\n" ); document.write( "24 = 3d
\n" ); document.write( "d = $\"24%2F3\"$
\n" ); document.write( "d = 8 yrs is Dianne's present age
\n" ); document.write( ":
\n" ); document.write( "That makes her Dad 16 yrs old (not realistic but satisfies the equation)
\n" ); document.write( ":
\n" ); document.write( "Check in the statement:
\n" ); document.write( "\"six years ago, Teddy was 5 times as old as his daughter\"
\n" ); document.write( "16 - 6 = 5(8 - 6)
\n" ); document.write( "10 = 5(2); confirms our solutions \n" ); document.write( "

\n" );
