1. **State the problem:** Solve the equation $14^x = -18$ for $x$. 2. **Understand the properties of exponential functions:** The function $14^x$ is an exponential function with base 14, which is positive and greater than 1. 3. **Important rule:** Exponential functions with positive bases always produce positive outputs for all real values of $x$. That is, $14^x > 0$ for all real $x$. 4. **Analyze the equation:** The right side of the equation is $-18$, which is negative. 5. **Conclusion:** Since $14^x$ can never be negative, there is no real solution to the equation $14^x = -18$. **Final answer:** No real solution exists because $14^x$ is always positive and cannot equal a negative number.
