$\"x2%2B6y%5E2=10\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"8x%5E2-y%5E2=15\"$
\n" ); document.write( "multiply by 6\r
\n" ); document.write( "\n" ); document.write( " $\"48x%5E2-6y%5E2=90\"$ \r
\n" ); document.write( "\n" ); document.write( "add up the equations\r
\n" ); document.write( "\n" ); document.write( " $\"49x%5E2=100\"$ \r
\n" ); document.write( "\n" ); document.write( "/49
\n" ); document.write( "x^2= 100/49\r
\n" ); document.write( "\n" ); document.write( "x= +/- 10/7\r
\n" ); document.write( "\n" ); document.write( "plug x and find two values of y\r
