What are the corresponding values on the Fahrenheit, Celsius, and Kelvin scales if two objects have equal temperatures?

Temperature on Fahrenheit and Celsius scales is calculated through

T(^oF) = 9/5 x T(^oC) + 32

Let the two objects have equal temperature reading of -40

X = Equal temperature reading on Fahrenheit (^oF) and Celsius (^oC) scales

Then

X = 9/5X x +32

And

X = -40

SO

T(^oF) = T(^oC) = -40

Corresponding value of temperature on Kelvin scale is calculated through

T(^oK) = T(^oC) + 273

SO, the corresponding temperature on Kelvin scale is

T(^oK) = 233
