let x = the 1st digit (and 4th)
\n" ); document.write( "let y = the 2nd digit (and 3rd)
\n" ); document.write( "let z = the last digit
\n" ); document.write( ":
\n" ); document.write( "A number where the first two digits are the reverse of 3rd & 4th digits
\n" ); document.write( "x, y, y, x, z
\n" ); document.write( ":
\n" ); document.write( "and the last digit is one-half of the first & double of the 2nd..??
\n" ); document.write( "z = .5x + 2y
\n" ); document.write( ":
\n" ); document.write( "For z to be a single digit; y =< 4; x has to be an even number
\n" ); document.write( "lets say y = 3, x = 4, then z = 8
\n" ); document.write( ":
