­If x and y are positive integers, what is the mean of x and y?

1) 2x+3y = 5
2) 7x-5y = 2

I don't understand how this is A. You can find multiple roots for each of these equations. This should be E.
­
Given that x and y are positive integers, the equation 2x + 3y = 5 has only one solution set, where x = 1 and y = 1. So, statement (1) is sufficient.

For statement (2), there are multiple solutions:

x = 6 and y = 8
x = 11 and y = 15
x = 16 and y = 22
x = 21 and y = 29
Thus, statement (2) is not sufficient.

This makes A the correct answer.

That said, if you check the post above, you’ll see this question can be ignored.­
