1. We are given the equation $12 + \frac{24}{4} - ? = 4$ and need to find the value of $?$. 2. First, simplify the term $\frac{24}{4}$ which equals $6$. 3. Substitute this back into the equation: $12 + 6 - ? = 4$. 4. Combine the known terms: $18 - ? = 4$. 5. To isolate $?$ subtract $4$ from both sides to get $18 - 4 = ?$. 6. Calculate $18 - 4$ which equals $14$. 7. Therefore, $?$ equals $14$. Final answer: $? = 14$.
