Wrote an equation for each statement
\n" ); document.write( ":
\n" ); document.write( "Darren is four times old as Tabitha.
\n" ); document.write( "d = 4t
\n" ); document.write( " In twenty years, Darren will be twice as old as Tabitha.
\n" ); document.write( "d + 20 = 2(t+20)
\n" ); document.write( "d + 20 = 2t + 40
\n" ); document.write( "d = 2t + 40 - 20
\n" ); document.write( "d =2t + 20
\n" ); document.write( "replace d with 4t from the 1st statement
\n" ); document.write( "4t =2t + 20
\n" ); document.write( "4t - 2t = 20
\n" ); document.write( "2t = 20
\n" ); document.write( "t = 10 yrs is Tabitha's age now
\n" ); document.write( "then
\n" ); document.write( "4(10) = 40 yrs is Darren's age
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in the statement
\n" ); document.write( "\"In twenty years, Darren will be twice as old as Tabitha. \"
\n" ); document.write( "40 + 20 = 2(10 + 20) \n" ); document.write( "
