To solve the equation \( \frac{x}{2} = 20 \) using inverse operations, follow these steps:
1. **Identify the operation:** The equation involves division by 2.
2. **Use the inverse operation:** The inverse of division is multiplication. To eliminate the division, multiply both sides of the equation by 2.
\[
2 \cdot \left(\frac{x}{2}\right) = 2 \cdot 20
\]
3. **Simplify both sides:**
\[
x = 40
\]
Therefore, the solution is \( x = 40 \).
