Hint: Adrian had been teaching 6 years longer than Betty.

Answer:
Adrian had been teaching 21 years.
Betty had been teaching 15 years.
Charlie had been teaching 7 years.
Adrian and Betty had been teaching for a total of 36 years.
Charlie and Betty had been teaching for a total of 22 years.
Charlie and Adrian had been teaching for a total of 28 years.
Let Adrian = A, Betty = B and Charlie = C, then:
A + B = 36 [1]
C + B = 22 [2]
C + A = 28 [3]
If we use [3] - [2] we have:
A - B = 6 [4]
If we use [1] + [4] we have:
2A = 42
A = 21
By [1] B = 15. By [3] C = 7. QED.
