To solve for \( x \) in the equation
\[ \frac{x}{0.2} + 3.3 = -16.2, \]
follow these steps:
- Isolate the fraction by subtracting \( 3.3 \) from both sides:
\[ \frac{x}{0.2} = -16.2 - 3.3. \]
- Perform the subtraction on the right side:
\[ -16.2 - 3.3 = -19.5. \]
Now the equation is:
\[ \frac{x}{0.2} = -19.5. \]
- Multiply both sides by \( 0.2 \) to solve for \( x \):
\[ x = -19.5 \times 0.2. \]
- Calculate the product:
\[ x = -3.9. \]
Thus, the solution is
\[ \boxed{-3.9}. \]
