Answer:
Explanation:
The expression "x + y" represents the sum of the values of x and y, while the expression "x - y" represents the difference between the values of x and y.
To evaluate these expressions, you need specific values for x and y. Let's consider an example where x = 5 and y = 3:
- For the expression "x + y," you substitute the values of x and y to get 5 + 3 = 8. So, "x + y" equals 8.
- For the expression "x - y," you substitute the values of x and y to get 5 - 3 = 2. So, "x - y" equals 2.
The expressions "x + y" and "x - y" can represent a variety of mathematical operations, depending on the values assigned to x and y. It's important to know the specific values of x and y in order to evaluate the expressions accurately.
