3. The attempt at a solution

this is actually a simple math question that i need a little help with. i know what the answer is because it was give in a student hand book but what i couldn't find is how the book came to the conclusions from equation (A and B) to get equation (C). If someone could point me in the mathmatical direction, it would be great

(A) 0 = A + b (-0.3)

(B) 100 = A + b (100.6)

solving A and B

Tc = A +bX = 0.2973 + 0.991X<-- how did they get A and B here?

where X = 18.2

and from equation Tc the true temperature is 18.33degrees celsius
