how will I equate it to get the final Temperature? I don't understand how did they get the answer of T=67.8 degrees Celsius.

can someone explain it? Pls. I have an Exam tomorrow and I need to understand it. thanks

**drwls**, Sunday, December 14, 2008 at 7:40amJust do the algebra to get the final T. Stick the units (degrees C) on later.

838.2*(T-70)+ 39(T-20)=0

(838.2+39) T = 58764 + 5800

T = 64564/878.2 = 73 C
