A digital machine uses a specific “Rule Box” to transform an input number (x)
into an output number. You need to decode the machine’s internal logic to find
the missing value. If the input and output of the machine are as follows:

Input (x) Output

5 19
8 28
12 40

? 31
If the machine just produced an output of 31. What was the original input
number fed into the machine?
