To solve the equation
\[
3 - 5 \cdot 3^x = 18,
\]
first, isolate the term involving \( x \):
\[
-5 \cdot 3^x = 18 - 3.
\]
This simplifies to:
\[
-5 \cdot 3^x = 15.
\]
Now, divide both sides by -5:
\[
3^x = -\frac{15}{5} = -3.
\]
Since \( 3^x \) (an exponential function) is always positive for real numbers, there is no real solution to the equation \( 3^x = -3 \).
Thus, the final answer is:
**No real solution.**

Let's solve the equation step by step. The given equation is:
\[
3 - 5 \cdot 3^x = 18.
\]
1. **Isolate the term containing \(3^x\)**:
Subtract 3 from both sides:
\[
-5 \cdot 3^x = 18 - 3 \implies -5 \cdot 3^x = 15.
\]
2. **Divide both sides by -5**:
\[
3^x = -\frac{15}{5} \implies 3^x = -3.
\]
At this point, we see that \(3^x\) (which represents an exponential function) always yields positive values for real \(x\). Therefore, \(3^x = -3\) has **no real solution**.
**Final conclusion**: There is no value of \(x\) that satisfies the equation \(3 - 5 \cdot 3^x = 18\) among real numbers.
