Recall the formula to convert Fahrenheit (F) to Celsius (C): \(C = \frac{5}{9} (F - 32)\).
Set the Celsius temperature equal to the Fahrenheit temperature to find the point where they are the same: \(C = F\).
Substitute \(C\) with \(F\) in the conversion formula: \(F = \frac{5}{9} (F - 32)\).
Multiply both sides of the equation by 9 to eliminate the denominator: \(9F = 5(F - 32)\).
Expand and solve for \(F\): \(9F = 5F - 160\), then rearrange to isolate \(F\) and find the temperature where both scales are equal.
