1. $\"2x+%2B+y+=+12\"$
\n" ); document.write( "2. $\"3x+-2y+=11\"$
\n" ); document.write( "From eq. 1,
\n" ); document.write( " $\"y=-2x%2B12\"$
\n" ); document.write( "Substitute in eq. 2,
\n" ); document.write( " $\"3x-2%28-2x%2B12%29=11\"$
\n" ); document.write( " $\"3x%2B4x-24=11\"$
\n" ); document.write( " $\"7x=35\"$
\n" ); document.write( " $\"highlight%28x=5%29\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"y=-2%285%29%2B12\"$
\n" ); document.write( " $\"y=-10%2B12\"$
\n" ); document.write( " $\"highlight%28y=2%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
