How many 2 digit integers are 6 times the sum of their digits?

Well if the number is ab where are and b are the digits then the number really is 10a+b

See if you can use that to help you. You need to make an equation.

Please no other answer give more, this is a good hint.

I can only think of 54.

[5 +4] x 6 = 54

That might be the only one

Have you set up an equation? If you do then it is easy to check all possibilities.
