This is the problem on my grandson's homework

The difference between two numbers is 361. What might the numbers be?

Show 2 different possible solutions?

Choose letters to represent the unknowns: x and y. We are told that x-y = 361.

We could choose any number for x and then calculate y:

Suppose we let x = 500. Then 500 - y = 361, and y = 139.

Suppose we let x = 1. Then 1 - y = 361, and y = - 360.

And so on.
