Answer:
middle brother = x
older brother = x+1
younger brother = x-1
x-1+x+x+1=129
3x+0=129
3x=129
x = 43(middle brother)
43-1 = 42(younger brother)
43+1 = 44(elder brother)
Check:
43-1+43+43+1=129
42+43+44=129
129=129

the answer is false because it can be in the Y or the X axis
The board is 12x larger in length than the nails. (Since the width of the board and nails are unknown, I am assuming you mean the length, not area difference)
