$\"x%2By=9\"$ ......eq. 1\r
\n" ); document.write( "\n" ); document.write( " $\"x=2y\"$ ...eq. 2......substitute in eq. 1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"2y%2By=9\"$ ...solve for $\"y\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"3y=9\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y=9%2F3\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"highlight%28y=3%29\"$ \r
\n" ); document.write( "\n" ); document.write( "now find $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=2y\"$ ....substitute $\"y\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=2%2A3\"$ \r
