Simple Puzzle of Three Hexagons

A simple puzzle based on the hexagonal tortoise problem.

The hexagonal tortoise problem was proposed by a Korean mathematician some 300 years ago. The N vertices of a hexagonal array are given numbers from 1 to N. The numbers are arranged so that the sum of the six integers at the vertices of each hexagon is the same. The original "magic" tortoise pattern, which contains 9 hexagons, was published in 1700. The sums of the integers at the vertices of each hexagon are 93. See - https://en.
