Let's call the numbers x and y, with x being the bigger of the two:
\n" ); document.write( "x+y = 45; y = 45-x
\n" ); document.write( "x-y =< 19
\n" ); document.write( "x-(45-x) =< 19
\n" ); document.write( "x-(-x+45) =<19
\n" ); document.write( "2x-45 =<19
\n" ); document.write( "2x =< 64
\n" ); document.write( "x=< 32
\n" ); document.write( "y=> 45-32 = 13
\n" ); document.write( "So your numbers, in (x,y) form, are:
\n" ); document.write( "(32,13), (31,14), (30,15), (29,16), (28,17) and so on, until you get to (23,22)\r
