Combining like terms just means putting together all the same variables. On the left side, 5x + x + x are all like terms and yoh get a total of 7x. Then -6 - 2 is -8. Left side in total is 7x - 8. As for the right side, is "a" a variable too?
75 degrees warmer.
If you subtract -39 by -114, you get 75 which is the distance between the two temperatures
