\n" ); document.write( "\n" ); document.write( "The pair  (x,y) = (3,1)  gives   x - y = 3-1 = 2.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The pair  (x,y) = (0,-4)  gives   x - y = 0-(-4) = 4.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The pair  (x,y) = (-4,0)  gives   x - y = -4-0 = -4.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The pair  (x,y) = (-3,-7)  gives   x - y = -3-(-7) = 7-3 = 4.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer.  Two pairs  (x,y) = (0,-4)  and  (x,y) = (-3,-7)  give   x - y = 4.\r
