A car accident victim, still under shock, was not able to remember the exact license plate of the car which ran him over. All he could remember was that it was composed by two letters, three numbers and again two letters, as displayed above. The letters, , can be described as numbers going from to . The numbers, , are all positive integers that go from 1 to 9, 0 is not included. Knowing that, the man said that:
Enter your answer under number form (eg: if you think the license plate number is ZB-974-JL, you'd have to enter 2629741012).

Let
and let's rewrite the properties of the license plate:
L1 + N1 = 7
L2/N3 = 4
N1 - L1 = N2
L4 = 4
L3 - N3 = 4
L1 = 1
L2 = 2xN1
Since L1 = 1, then N1 = 7 - 1 = 6.
N2 = N1 - L1 = 6 - 1 = 5.
L2 = 2 x N1 = 2 x 6 = 12.
N3 = L2/N3 = 12/4 = 3.
L3 = 4 + N3 = 7.
So, the correct answer is 11265374 (or, with the actual letters AL653GD).
