\n" ); document.write( " $\"x%2By=6\"$ .......eq.1
\n" ); document.write( " $\"x-y=2\"$ .......eq.2
\n" ); document.write( "----------------------add both\r
\n" ); document.write( "\n" ); document.write( " $\"x%2By%2Bx-y=6%2B2\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"2x%2Bcross%28y%29-cross%28y%29=8\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=8%2F2\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=4\"$ \r
\n" ); document.write( "\n" ); document.write( "go to $\"x%2By=6\"$ .......eq.1 plug in $\"x\"$ value\r
\n" ); document.write( "\n" ); document.write( " $\"4%2By=6\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y=6-4\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y=2\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
