Step-by-step explanation: If you double the reversed number (68) you would get 136 then add 86 to that orignal sum and you get 222 voila. How i got the number was I did guess and check.
To figure this equation out I used a guess and check strategy. I looked at all combinations of digits that gave us a sum of 14. When I got to 86, and reversed the digits, I ended up getting 136. When I added 136 to 86 it was 222. We started with seven and seven, and then looked at eight and six and a six and eight. Eight in six was that right combination!
Hope this helps!!
Please tell me if I am incorrect I enjoy learning from my mistakes.
