Initial number, \"10t%2Bu\".\r

\n" ); document.write( "\n" ); document.write( "\"system%282t=17%2Babs%28t-u%29%2C10u%2Bt-%2810t%2Bu%29=9%29\"\r

\n" ); document.write( "\n" ); document.write( "The difference equation becomes \"10u%2Bt-10t-u=9\"

\n" ); document.write( "\"highlight_green%28u-t=1%29\".\r

\n" ); document.write( "\n" ); document.write( "Handling the absolute value equation gives these two possible equations:
\n" ); document.write( "\"system%28t-u%2B17=2t%2Cor%2C-t%2Bu%2B17=2t%29\"

\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Either or both of the results of the absolute value equation may work. Start with the \"non-negative\" form to remake the system.
