Me and my dad are trying to figure out the answer for number 13 but we keep getting the answer 3 but it isn't right. Can you help?
**Transcription for Educational Use**

This document seems to contain a series of algebraic equations, along with steps showing their solutions. Below is the transcription and explanation for each problem:

---

**Equation 7**:
\[ 3(-2 - 3x) = -9x - 4 \]

Solution Steps:
1. Distribute the 3: \( -6 - 9x = -9x - 4 \)
2. Add 9x to both sides: \( -6 = -4 \)
3. \( x = \) (no solution found)

---

**Equation 9**:
\[ 9(4b - 1) = 2(9b + 3) \]

Solution Steps:
1. Distribute: \( 36b - 9 = 18b + 6 \)
2. Rearrange: \( 18b = 15 \)
3. Solve for \( b \): \( b = \frac{15}{18} = \frac{5}{6} \)

---

**Equation 11**:
\[ -5x - 10 = 2 - (x + 4) \]

Solution Steps:
1. Expand: \( -5x - 10 = 2 - x - 4 \)
2. Combine like terms: \( -5x - 10 = -x - 2 \)
3. Add 5x and 2 to both sides: \( -10 + x = 8 \)
4. Solve for \( x \): \( x = 8 \)

---

**Equation 13**:
\[ \frac{5}{2}t - t = 3 + \frac{3}{2}t \]

Solution Steps:
1. Combine terms: \( \frac{3}{2}t = 3 + \frac{3}{2}t \)

---

**Equation 15**:
\[ \frac{2}{3}x - \frac{1}{6} = \frac{1}{2}x + \frac{5}{6} \]

Solution Steps:
1. Rearrange terms.
2. Find a common denominator to solve for \( x \).

---

**Equation 17**:
\[ \frac{1}{2}(3g - 2) = \frac{g}{2} \]

Solution Steps:
1. Distribute to clear the fraction.
2. Simplify the equation
