Carl's hands trembled as he stood in front of the safe and unfolded the crumpled piece of paper holding the combination that would open the sage. "Rats!" he moaned. The combination was written in the form of a riddle. The last number was described in the following way: Find 2/3 of the final number, add 16, and this number will be equal to two times the mystery number. What was the final number of the combination?
