1. $\"x%2By=56\"$
\n" ); document.write( "2. $\"x%2B3y=56\"$
\n" ); document.write( "You can re-write eq. 2,
\n" ); document.write( " $\"x%2By%2B2y=56\"$
\n" ); document.write( "Substitute,
\n" ); document.write( " $\"%2856%29%2B2y=56\"$
\n" ); document.write( " $\"2y=0\"$
\n" ); document.write( " $\"highlight%28y=0%29\"$
\n" ); document.write( "Then from eq. 1,
\n" ); document.write( " $\"x%2B0=56\"$
\n" ); document.write( " $\"highlight%28x=56%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
