Answer:
We can add 53.6 in both sides and we got:
And now we can divide both sides by 2 and we got:
Step-by-step explanation:
For this case we know the following info:
represent the coldest temperature in the Moon
represent the minimum temperature of Earth
And we know the following relation :"the coldest surface temperature on the Moon, $-280$°F, is $53.6$°F colder than twice the coldest surface temperature on Earth", so we can write this like that:
We can add 53.6 in both sides and we got:
And now we can divide both sides by 2 and we got:
