The function ‘t’ which map temperature in Celsius (C) into temperature in Fahrenheit (F) is defined by t(C) = F where F = `9/5` C + 32. Find, the temperature when the Celsius value is equal to the Fahrenheit value
उत्तर
Given t(C) = `9/5` C + 32
consider the value of C be “x”
t(C) = `9/5` C + 32
x = `9/5` x + 32
5x = 9x + 160
– 160 = 9x – 5x
– 160 = 4x
x = `(-160)/4` = – 40
The temperature when the Celsius value is equal to the fahrenheit value is – 40°
