What is that temperature at which the Fahrenheit reading is double that of the Celsius reading?

Explanation

To find the temperature at which the Fahrenheit reading is double that of the Celsius reading, we can follow these steps:

### Step-by-Step Solution:

1. **Define the Variables**:
Let the temperature in Celsius be \( T \) (in °C). According to the problem, the Fahrenheit reading \( F \) should be double that of the Celsius reading. Therefore, we can express this as:
\[
F = 2T
