Let's go through and solve each of these equations step by step, and then match the answers to the choices provided.

1. **Equation 1:**
   \[
   \frac{x + 2}{3} = \frac{2x - 4}{2}
   \]
   Multiply both sides by 6 to eliminate the denominators:
   \[
   2(x + 2) = 3(2x - 4)
   \]
   Simplify:
   \[
   2x + 4 = 6x - 12
   \]
   Move terms involving \(x\) to one side:
   \[
   4 + 12 = 6x - 2x
   \]
   Simplify:
   \[
   16 = 4x \quad \Rightarrow \quad x = 4
   \]

2. **Equation 2:**
   \[
   \frac{7}{4x} - \frac{3}{2x} = \frac{1}{2x^2}
   \]
   Multiply through by \(4x^2\) to clear the denominators:
   \[
   7x - 6x = 2
   \]
   Simplify:
   \[
   x = 2
   \]

3. **Equation 3:**
   \[
   \frac{2x}{x+1} + \frac{5}{2x} = 2
   \]
   Multiply through by \(2x(x+1)\) to eliminate fractions:
   \[
   4x^2 + 10(x + 1) = 4x(x+1)
   \]
   Simplify and solve.

4. **Equation 4:**
   \[
   \frac{x^2 - 1}{x - 3} = \frac{8}{x - 3}
   \]
   Cancel out \(x - 3\) (assuming \(x \neq 3\)):
   \[
   x^2 - 1 = 8 \quad \Rightarrow \quad x^2 = 9 \quad \Rightarrow \quad x = \pm 3
   \]
   Since \(x \neq 3\), the solution is \(x = -3\).
