Solution Steps

Step 1: Start with the equation $2.718^{-3x} = 9$.
Step 2: Take the natural logarithm (ln) of both sides to get $ln(2.718^{-3x}) = ln(9)$.
Step 3: Use the property of logarithms to bring the exponent in front: $-3x \cdot ln(2.718) = ln(9)$.
Step 4: Solve for $x$ by isolating it: $x = \frac{ln(9)}{-3 \cdot ln(2.718)} = -0.73$.

Final Answer

$x = -0.73$
