Answer 1

Hey there! Welcome to QuestionCove!!

Looks like your question is missing some numbers. They got lost when you copy-pasted

But it's a really simple question
If the temperature was x
And it becomes y degrees colder

Then what's the temperature?

So you have to remember that the higher the temperature means the hotter it's getting, so if it got y degrees colder, that means we have to subtract

So
x - y


If, for example, instead it said that it got WARMER or hotter by 'y' degrees then we would do x+y
