Question

15 increased by a number equals 27

Answer 1

12

X+15=27

-15 -15

x=12

Answer 2

The equation for that would be n+15=27

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
