Answer 1

Let's evaluate each question one by one:

**Question 1:** Solve the equation \( 10x = 90 \).

To solve for \( x \):
- You can divide both sides by 10:

\[
x = \frac{90}{10} = 9
\]

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

---

**Question 2:** Solve the equation \( \frac{x}{13} = 39 \).

To solve for \( x \):
- You can multiply both sides by 13:

\[
x = 39 \times 13 = 507
\]

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

---

**Question 3:** Solve the equation \( 14x = 56 \).

To solve for \( x \):
- You can divide both sides by 14:

\[
x = \frac{56}{14} = 4
\]

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

---

To summarize:
1. Divide both sides by 10; x = 9.
2. Multiply both sides by 13; x = 507.
3. Divide both sides by 14; x = 4.
