Let Katrina's age be K, and Nico's age be N.\r
\n" ); document.write( "\n" ); document.write( "Katrina's age is twice of Nico's. K=2N
\n" ); document.write( "The sum of their ages is 36. K+N=36.\r
\n" ); document.write( "\n" ); document.write( "You can use substitution to get 2N+N=36 3N=36 N=12\r
\n" ); document.write( "\n" ); document.write( "We plug it back in to get Katrina's age. K=2N K=2(12) K=24.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Katrina's 24, Nico's 12.
