1. $\"2x-5y+=+-19\"$
\n" ); document.write( "2. $\"y+=+x%2B2\"$
\n" ); document.write( "Substitute eq. 2 into eq. 1,
\n" ); document.write( " $\"2x-5%28x%2B2%29=-19\"$
\n" ); document.write( " $\"2x-5x-10=-19\"$
\n" ); document.write( " $\"-3x=-9\"$
\n" ); document.write( " $\"highlight%28x=3%29\"$
\n" ); document.write( "Then from eq. 2,
\n" ); document.write( " $\"y=3%2B2\"$
\n" ); document.write( " $\"highlight%28y=5%29\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
