To find: The temperature at which both temperature scales Fahrenheit and Celsius agree.
(b)

Answer to Problem 70E
The temperature at which both temperature scales Fahrenheit and Celsius agree, is
Explanation of Solution
Given:
The equation that determines the relationship between the Fahrenheit
Calculation:
Let, a is the temperature at which both temperature scales agree.
Substitute a for F and C in equation (1) and find the value of a,
Above equation gives the value of a is,
Thus, The temperature at which both temperature scales Fahrenheit and Celsius agree, is
