You can put this solution on YOUR website!
You should eliminate the y^2; or do this:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"system%28y%5E2=4-x%5E2%2Cand%2Cy%5E2=4%2Bx%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "and from this, \"4-x%5E2=4%2Bx\"----now solve this and use for finding y.
\n" ); document.write( "
\n" );
