Answer 1

Let's evaluate each question and determine the true statements.

**Question 1: 10x = 90**
- If we divide both sides by 10, we get:
\[ \frac{10x}{10} = \frac{90}{10} \]
\[ x = 9 \]

The true statement is:
- **Divide both sides by 10; x = 9.**

---

**Question 2: x/13 = 39**
- If we multiply both sides by 13, we get:
\[ 13 \cdot \frac{x}{13} = 39 \cdot 13 \]
\[ x = 507 \]

The true statement is:
- **Multiply both sides by 13; x = 507.**

---

**Question 3: 14x = 56**
- If we divide both sides by 14, we get:
\[ \frac{14x}{14} = \frac{56}{14} \]
\[ x = 4 \]

The true statement is:
- **Divide both sides by 14; x = 4.**

---

So, for each question:
1. **Divide both sides by 10; x = 9.**
2. **Multiply both sides by 13; x = 507.**
3. **Divide both sides by 14; x = 4.**
