Verified step by step guidance

1. Understand the relationship between Fahrenheit and Celsius. The formula to convert Celsius to Fahrenheit is: $F=\frac{9}{5}C+32$.
2. Set up the equation where the temperature in Fahrenheit is equal to the temperature in Celsius: $F=C$.
3. Substitute the expression for Fahrenheit from the conversion formula into the equation: $\frac{9}{5}C+32=C$.
4. Solve the equation for $C$. Start by isolating $C$ on one side of the equation. Subtract $C$ from both sides: $\frac{9}{5}C-C=-32$.
5. Combine like terms and solve for $C$. This will give you the temperature at which Fahrenheit equals Celsius.
