\"Five years ago, Tom was one third as old as his father was then\" ___ 3(t - 5) = f - 5 ___ 3t - 15 = f - 5 ___ 3t - 10 = f\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"In 5 years, Tom will be half as old as his father will be then\" ___ 2(t + 5) = f + 5 ___ 2t + 10 = f + 5 ___ 2t + 5 = f\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting ___ 2t + 5 = 3t - 10 ___ 15 = t\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting ___ 2(15) + 5 = f ___ 35 = f
\n" ); document.write( "
