Look at the first part. xy = 4y + 2. Check y values:


\n" ); document.write( "y=1 and 4*1 + 2 = 6. Can't be, because that's only 1 digit.
\n" ); document.write( "y=2 and 4*2 + 2 = 10. Can't be, because the second digit is 0, not 2.
\n" ); document.write( "y=3 and 4*3 + 2 = 14. Can't be.
\n" ); document.write( "y=4 and 4*4 + 2 = 18. No
\n" ); document.write( "y=5 and 4*5 + 2 = 22. No.
\n" ); document.write( "y=6 and 4*6 + 2 = 26. 26 is possible. y is 6 in the result. So check it against the second parameter.


\n" ); document.write( "62 = 2*26 + 10 = 62 Yes!
\n" ); document.write( "
