Answer:
n= 12
Step-by-step 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=12
12.
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.
