1. **State the problem:** Solve the linear equation $4x - 7 = 7x + 5$ for $x$.
2. **Write the formula and rules:** To solve for $x$, we want to isolate $x$ on one side. We do this by moving all terms with $x$ to one side and constants to the other.
3. **Step-by-step solution:**
- Start with the equation:
$$4x - 7 = 7x + 5$$
- Subtract $7x$ from both sides to get all $x$ terms on the left:
$$4x - 7x - 7 = 7x - 7x + 5$$
$$\cancel{4x} - \cancel{7x} - 7 = 0 + 5$$
$$-3x - 7 = 5$$
- Add $7$ to both sides to move constants to the right:
$$-3x - 7 + 7 = 5 + 7$$
$$-3x = 12$$
- Divide both sides by $-3$ to solve for $x$:
$$x = \frac{12}{-3}$$
$$x = -4$$
4. **Final answer:**
$$\boxed{x = -4}$$
This means the value of $x$ that satisfies the equation is $-4$.
