\n" ); document.write( "x = cows = 39
\n" ); document.write( "y = pigs = 60
\n" ); document.write( "z = horses = 1
\n" ); document.write( "---
\n" ); document.write( "NOTE:
\n" ); document.write( "the problem statement says to \"buy one of each animal at least\", so I started with x=1, but that gave a fractional number of animals, then I tried y=1 and that too gave a fractional number of animals, finally I tried z=1, which gave the integer number of animals shown in the solution.
