15 increased by a number equals 27

The equation for that would be n+15=27

Step-by-step explanation:

We can use any variable to represent 'a number'.

W will add since the value is getting increased by n

n+15=27

If we wanted to solve this, we would subtract 15 from 27 to get 12=n

hope this helps :)
