\n" );
document.write( "2/x + 1/y = 0
\n" );
document.write( " 5/x + 2/y = -5 
\n" );
document.write( "'u' = 1/x and 'v' = 1/y ****\r
\n" );
document.write( "\n" );
document.write( "2u + v = 0   |multiplying thru by -2 to  eliminate the v variable
\n" );
document.write( "5u + 2v = -5 
\n" );
document.write( "  u = -5   and v = 10 
\n" );
document.write( " x = 1/-5   and v = 1/10
\n" );
document.write( "and...
