If b is the midpoint, that means AB and BC are the same lengths, so 10x-8=5x+17. Subtract 5x from both sides: 5x-8=17. 
Add 8 to both sides: 5x=25
Divide by 5 and find that x=5.

The answer is 573

S is the three digit number.
h - a number of hundreds
t - a number of tens
o - a number of ones

S = 100h + 10t + o

<span>The last two digits add to make ten: t + o = 10
</span><span>The first and last digits add to make eight: h + o = 8
</span><span>The first two digits add to make twelve: h + t = 12

</span>t + o = 10          ⇒ o = 10 - t
h + o = 8           ⇒ o = 8 - h
_______
10 - t = 8 - h
h + t = 12          ⇒ h = 12 - t
_______
10 - t = 8 - (12 - t)
10 - t = 8 - 12 + t
10 - t = -4 + t
10 + 4 = t + t
2t = 14
t = 14/2 = 7
______

h = 12 - t = 12 - 7 = 5
______

o = 8 - h = 8 - 5 = 3

S =  100h + 10t + o
h = 5
t = 7
o = 3

S = 100*5 + 10*7 + 3
   = 500 + 70 + 3
   = 573
