If 4x-y=2/3, what is the value of $\"81%5E%283x%29%2F27%5Ey\"$
\n" ); document.write( "we can rewrite this to
\n" ); document.write( " $\"%283%5E4%29%5E%283x%29%2F%283%5E3%29%5Ey\"$
\n" ); document.write( "which is
\n" ); document.write( " $\"3%5E%2812x%29%2F3%5E%283y%29\"$ = $\"3%5E%2812x-3y%29\"$ = $\"3%5E%283%284x-y%29%29\"$ = $\"27%5E%28%284x-y%29%29\"$
\n" ); document.write( ":
\n" ); document.write( "Note that the equation is 4x-y = 2/3, therefore
\n" ); document.write( "we can replace 4x-y with 2/3 so be now have
\n" ); document.write( " $\"27%5E%28%282%2F3%29%29\"$ = 9 \n" ); document.write( "

\n" );
