\n" ); document.write( "13(x-?)=3(x-?)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Try:
\n" ); document.write( "3(s+c)=39
\n" ); document.write( "13(s-c)=39
\n" ); document.write( "Two equations with two unknowns
\n" ); document.write( "rate in still water (s) and current (c)\r
