Question

27=15+n I can not get this one ether

Answer 1

12.

Explanation:

We don't have the other number, so we must do the reverse operation, which is subtraction. So we have to subtract 27 from 15. 7-5 is 2, and 20-10 is 10. Add those together and you get 12.

Answer 2

n= 12

Explanation:

27=15+n

step 1. simplify

27=n+15

step 2. flip the equation n+15=27

step 3. subtract 15 from both sides

n+ 15 - 15 = 27 - 15 =

n=12
