x^2+y^2=63
\n" ); document.write( "x^2-3y^2=27
\n" ); document.write( "----------- Subtract
\n" ); document.write( "4y^2 = 36
\n" ); document.write( "y = +/- 3
\n" ); document.write( "----------
\n" ); document.write( "Sub for y and find values of x
\n" ); document.write( "x^2 + 9 = 63
\n" ); document.write( "x = +/- 3sqrt(2)
\n" ); document.write( "Use the + and minus values to get the 4 points of intersection.
