RAW TAIL  other divisors. For example, 56 divided by something. Wait, 56 is 56. Divisors are 1,2,4,7,8,14,28,56. So yes, only 28 and 56. Therefore, two bases. Therefore, answer is 70.

But just to check, let me think if there is any other way that 56/(b + 7) is integer. For example, maybe if b + 7 is a divisor of 56, but maybe negative? But since b is greater than 9, b + 7 is positive. Therefore, no.

Alternatively, maybe I can check if there's an error in my first approach. For example, when I did the division, I said that 9b + 7 divided by b + 7 is 9 - 56/(b + 7). Let me check that again.

Let me perform the division:

Divide 9b + 7 by b + 7.

How many times does b + 7 go into 9b + 7? Well, 9 times. Multiply 9*(b + 7) = 9b + 63. Then subtract that from 9b + 7:

(9b + 7) - (9b + 63) = 7 - 63 = -56. Therefore, the remainder is -56. Therefore, the division is 9 with a remainder of -56. Therefore, (9b + 7) = 9*(b + 7) - 56. Therefore, (9b + 7)/(b + 7) = 9 - 56/(b + 7). Therefore, correct. Therefore, that is correct.

Therefore, 56/(b + 7) must be integer. Therefore, b + 7 divides 56. Therefore, same conclusion.

Therefore, answer is 70. Therefore, I think that is correct.

But just to check, let me check if there are other possible divisors. Wait, 56 is 56. Divisors are as above. So 28 and 56. Therefore, only two bases. Therefore, answer is 70. Therefore, the answer is 70. So I think that is correct.

Wait, but let me check if there's another possible value. For example, if b + 7 is 14? Then b is 7. But b must be greater than 9. So 14 is less than 16. So no. Similarly, 8 is less. So no. Therefore, only 28 and 56. Therefore, yes.

Alternatively, maybe I can check if there's another way. For example, if I write the equation:

Let me suppose that (9b + 7) is divisible by (b + 7). Therefore, (b + 7) divides (9b + 7). Therefore, (b + 7) divides any linear combination of (9b + 7) and (b + 7). For example, let me compute 9*(b + 7) - (9b + 7) = 9b + 63 - 9b - 7 = 56. Therefore, (b + 7) divides 56. Which is the same conclusion as before. Therefore, that's another way to see it. Therefore, same result.

Therefore, I think that the answer is 70. Therefore, the sum is 21 + 49 = 70. Therefore, the answer is 70. Therefore, I think that is correct.

**Final Answer**
\boxed{70}
</think>

To solve the problem, we are given two numbers in base $ b $: $ 17_b $ and $ 97_b $. We are to find the sum of all integer bases $ b > 9 $ for which $ 17_b $ is a divisor of $ 97_b $.

---

### Step 1: Convert the Numbers to Base 10

In base $ b $, the number $ 17_b $ represents:

$$
1 \cdot b + 7 = b + 7
$$

Similarly, $ 97_b $ represents:

$$
9 \cdot b + 7 = 9b + 7
$$

So, the problem becomes: Find all integers $ b > 9 $ such that $ b + 7 $ divides $ 9b + 7 $, i.e.,

$$
\frac{9b + 7}{b + 7} \in \mathbb{Z}
$$

---

### Step 2: Simplify the Expression

We simplify the fraction:

$$
\frac{9b + 7}{b + 7}
$$

We perform polynomial division:

$$
\frac{9b + 7}{b + 7} = 9 - \frac{56}{b + 7}
$$

This shows that the expression is an integer **if and only if** $ b + 7 $ divides 56.

So, we are looking for all **positive integers $ b > 9 $** such that $ b + 7 $ is a **positive divisor of 56**.

---

### Step 3: Find the Relevant Divisors

The positive divisors of 56 are:

$$
1, 2, 4, 7, 8, 14, 28, 56
$$

We are looking for those $ d = b + 7 $ such that $ d > 16 $ (since $ b > 9 \Rightarrow b + 7 > 16 $).

From the list, the divisors of 56 greater than 16 are:

$$
28, 56
$$

Therefore:

- If $ b + 7 = 28 $, then $ b = 21 $
- If $ b + 7 = 56 $, then $ b = 49 $

---

### Step 4: Verify and Sum the Valid Bases

Check that both 21 and 49 are valid:

- $ 17_{21} = 21 + 7 = 28 $
- $ 97_{21} = 9 \cdot 21 + 7 = 196 $, and $ 196 \div 28 = 7 $, so 28 divides 196.

- $ 17_{49} = 49 + 7 = 56 $
- $ 97_{49} = 9 \cdot 49 + 7 = 448 $, and $ 448 \div 56 = 8 $, so 56 divides 448.

Thus, both 21 and 49 are valid bases.

---

### Final Answer

The sum of all such bases is:

$$
21 + 49 = \boxed{70}
$$

- $ 97_{49} = 9 \cdot 49 + 7 = 448 $, and $ 448 \div 56 = 8 $, so 56 divides 448.

Thus, both 21 and 49 are valid bases.
