72 + 14 = 86 86 ÷ 2 = ** 43
**So in the end you see this really isn't a very complicated question because the answer is 43
The original number is 43. By setting up the equation from the described process and solving for x , we find the result. Doubling 43 and decreasing by 14 gives us 72, confirming our solution.
