Answer:
x = 4
Step-by-step explanation:
3x - 6y = 18
2x + 2y = 6 -> 3(2x + 2y = 6)
3x - 6y = 18 -> Cross out - 6y
6x + 6y = 18 -> Cross out + 6y
9x = 36 -> Divide 9 on both sides.
X = 4

I don’t get what your trying to ask
Considering the temperature at midnight, it is found that the temperature at noon was of 16.6ºF.
<h3>What was the temperature at noon.</h3>
Between noon and midnight, the temperature went down by 23.8°F, meaning that the temperature at noon is the <u>midnight's temperature if -7.2 ºF added to 23.8 ºF</u>, hence:
-7.2 + 23.8 = 16.6ºF.
The temperature at noon was of 16.6ºF.
