Answer:
The number is 5
Step-by-step explanation:
lets say n = number, the problem It says -5 is subtracted from a number which can be written as n-(-5) and remember that when there are 2 negatives together it's positive so you add, so we write it as n+5. the problem now says the result is 10, that means the sum should add up to 10 so you write it as n+5=10.
Now we have to isolate n so we move 5 to the other side of equations and it becomes negative so now it will look like n=10-5. now the answer is n=5
Let's plug it in
5-(-5)=10 Now we now it's correct and the result is 10
