Final answer:
An example of an odd number x and an even number y that satisfy the equation x - y = 7 is x = 15 and y = 8.
Step-by-step explanation:
To find an example of an odd number x and an even number y such that x - y = 7, we can choose x = 15 and y = 8. In this case, 15 - 8 equals 7, which satisfies the given equation.
