Well the - 5 is subtracted from a number the result is 10 find the number

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
