a1 + a2 = 8 and a2 + b2 = 8. So a1 + a2 = a2 + b2 which gives a1 = b2.
Now take b1 - b2 = 6 and using a1 = b2 we get b1 - a1 = 6.
we have a1 + b1 = 13, So adding these two equations we get 2b1 = 19, So b1 = 9.5
It is easy to get remaining values from the remaining equations.

Calculate the number of ordered triples (A1, A2, A3) such that:

A1 ∪ A2 ∪ A3 = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
A1 ∩ A2 ∩ A3 = ∅

Write your answer as 2a3b5c7d where a, b, c, d are non-negative integers.
