Data Sufficiency (DS) | Re: In the diagram above each of the letters represents one of the digits

I may have the answer to this:
From question: the numbers can only be 6, 7, or 8 and each letter is a distinct number
Statement 1:
b + m = 15

So b and m can be 7 or 8, can not be 6.
Look at the figure, if we know the value of b then a ,x, c, l (all the number next to it) can't have that value. Also, iof we know m, we know what k, l, c, z can't be.
So if b and m can be either 7 or 8, then c and l can be either 7 or 8, and only can be 6.

And if c = l = 6, a and k can't be 6, therefore w must be
