Final answer:
The equation that could represent Diego's two numbers is x + y = [answer2].
Step-by-step explanation:
Let's represent Diego's two numbers using variables. Let's say the first number is x and the second number is y. The equation that could represent this description is x + y = [answer2].
For example, if [answer2] is equal to 10, then the equation would be x + y = 10.
Diego's two numbers can be any pair of numbers that satisfy this equation.
