Brandi · Answer 1

Let the Addison's candy count be a and Ronny's be r.

Then a = r - 15. This is an equation.

If you had a second equation, you could replace a with the expression (r - 15), which in itself is not an equation.

Rylie Munoz · Answer 2

Let Ronny's candy be x and Addison's candy be y. Then it would read y=x-15.

This is an equation because this is saying that Ronny's amount of candy minus 15 is equal to amount of candy that Addison has. Once there is a useful equal then it is equation.
