i am not sure is this is correct but, I think that x+5 that x is 27 and the other one is 12 and the 27+5 is 32 and 32+12 is 44 so i am guessing that the BD side is 44, i guess and about the other , the first black space is parallel and the second is equals half
The simple and easiest way to find it is that you add all the numbers of that value i.e.: 1485=1+4+8+5 it will give u a number which will tell u if it is divisible by what number i mean that: 1+4+8+5=18 so 18 is divisible by 2, 3, 6, and 9
