1. **State the problem:** Solve the equation $4m - 4 = 4m$ for $m$. 2. **Write down the equation:** $$4m - 4 = 4m$$ 3. **Subtract $4m$ from both sides to isolate terms:** $$4m - 4 - 4m = 4m - 4m$$ 4. **Simplify both sides:** $$-4 = 0$$ 5. **Analyze the result:** The statement $-4 = 0$ is false, which means there is no value of $m$ that satisfies the equation. 6. **Conclusion:** The equation has **no solution** because it leads to a contradiction.
