Four lettered dials (A, B, C, D) unlock a vault. Each dial must be set to the correct number based on the clues below. Solve all clues to find the code: the 4-digit number ABCD.
Crack the vault code using these clues:
– A – B = D
A + B = 10
C = (B + D + 4) ÷ 2
A is an even number greater than 4.
D + A + C + B = 22
C = D
