Please answer. Thanks!

Step-by-step explanation:

So you know the difference is 13. Therefore

x - y = 13

You also know the larger number is 1 less than twice the smaller one. Since 13 is positive, it's safe to assume the first one is larger. So in essence, the larger number (x) is 2 times bigger than the smaller (= 2y...), but one less than that (= 2y - 1)

Therefore

X = 2y - 1

No you can plug in this little expression for x in your original equation:

(2y - 1) - y = 13

And solve for y! Don't forget to distrivute, and to find x, plug the y value you get back into the original (x - y = 13) and solve for x.

Happy calculating! (:
