1. $\"y+=+x+-+2\"$
\n" ); document.write( " $\"4x+%2B+4y+=+8\"$
\n" ); document.write( "2. $\"x%2By=2\"$
\n" ); document.write( "Directly substitute eq. 1 into eq. 2,
\n" ); document.write( " $\"x%2B%28x-2%29=2\"$
\n" ); document.write( " $\"2x-2=2\"$
\n" ); document.write( " $\"2x=4\"$
\n" ); document.write( " $\"highlight%28x=2%29\"$ \n" ); document.write( "
